Computer Numerical Control (CNC) Is The Heart of Modern Manufacturing

1

Manufacturing products that requires precise measurements requires cutting edge precision and nimbleness from the worker. Most of the time manufacturing these kinds of products requires weeks or months to finish therefore slowing down productivity as well as consistency of the manufacturers.

In modern systems, end-to-end component design is highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine via a postprocessor, and then loaded into the computer numerical control (CNC) machines for production.

Computer numerical control has been around since the early 1970’s. It’s a method used in modern machining to perform a wide range of associated tasks.  Prior to this, it was called NC, for numerical control. In the early 1970’s computers were introduced to these controls, hence the name changed.  Virtually every piece of metalworking equipment is available in the CNC variation. Some are discuss below:

Metal fabrication, Computer Numerical controlled Lathe’s are used to fabricate metal sheet by shearing, flame or plasma cutting, punching, laser cutting, forming and welding. Most CNC Lathe’s are used for designing modern carbide tooling. The design could be created with the Computer Aided Manufacturing (CAM) process, and when done, the CNC could start creating the product automatically with little supervision from the machine operator.

Surface grinding is used to produce a smooth finish on flat surfaces.CNC surface grinding is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or non metallic substance from a workpiece, making a face of it flat or smooth with a great accuracy since is computer numeric controlled.

Drilling is the most common machine process. Computer Numerical Controlled Drilling is used to create precise right circular cylinders over a certain material, the CNC could be programmed to create holes on different standards. Drilling is commonly used in wood working manufacturing process in which other process is also involved such as milling, turning and grinding.

water jet cutter, also known as a waterjet, is a tool capable of slicing into metal or other materials (e.g. granite) using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance. The process is essentially the same as water erosion found in nature but greatly accelerated and concentrated. It is often used during fabrication or manufacture of parts for machinery and other devices. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods. When water jet cutter is CNC based, a good result is inevitable.

Electrical discharge machining (EDM) is the process of removing metal with the use of electrical sparks to take away the metal. CNC Electrical Discharge Machine has two types, the vertical EDM and wire EDM. Vertical EDM uses an electrode that is the shape of the cavity to be machined into a work piece. Wire EDM is used to create punch and die combinations in the fabrication industry. Computer Numerical Control EDM’s are not usually known because it is mostly incorporated to other CNC process.

Plasma cutting is a process that is used to cut steel and other metals of different thicknesses (or sometimes other materials) using a plasma torch. In this process, an inert gas (in some units, compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the cut. CNC plasma equipment is capable of multi-axis cutting of thick material, allowing opportunities for complex welding seams on CNC welding equipment that is not possible otherwise.

Hot-wire foam cutter is a tool used to cut polystyrene foam and similar materials. The CNC hot-wire foam cutter device consists of a thin, taut metal wire, often made of nichrome or stainless steel, or a thicker wire preformed into a desired shape, which is heated via electrical resistance to approximately 200°C. As the wire is passed through the material to be cut, the heat from the wire vaporises the material just in advance of contact. Because it is CNC based, the precision is always very high.

With the efficiency of CNC machining in addition to its speed of production and optimum raw material usage, it’s easy to see why CNC machining is the gold standard of metalworking and part fabrication.

Today, many people build and run small CNC machining shops in their own garages or basements. This is an area of tremendous interest for many hobbyists looking for a new challenge. From creating its own metal fabrications and wood crafts to computer-controlled punching applications, CNC machining has opened a whole new world for creative minds to find new ways of making their visions come to life.

There is quite a shortage of skilled people to utilize CNC machines. And the shortage is growing.

Nigeria Does Better in Business Environment Than Attractiveness In Financial Industry, Says Accenture

1

You better not ask what is the difference between being attractive for business and business environment. According to the global outsourcing and consulting giant, Accenture, they are different. Nigeria is better in business environment – lesser regulation while we are not attractive perhaps due to low purchasing power and high competition in the domain of the financial services. South Africa leads the pack in both ways. This is how Accenture saw it in a new report.

 

Meanwhile, Accenture has some good suggestions on how to enter African markets. They recognize the diversity of culture and different market conditions across the continent.

 

All companies interested in expanding in Africa—not just those in financial services—face several key  decisions on how to approach the market. The diversity and complexity of individual country markets mean that a single pan-African strategy will likely fall short. Instead, organizations should consider a set of four focused actions.
1. Scan the landscape. Create a dedicated Africa task force to identify and understand the relative attractiveness of different markets and sectors, and the specialist skills and competitive advantages the company can bring to those it chooses to enter.
2. Establish beachheads. Take small positions in local institutions as a base from which to seize emerging growth opportunities.
3. Develop local models. Design, build and operate models that reflect, and are focused on meeting, specific local market needs.
4. Build ecosystems. Seek out and establish partnerships, alliances and networks to help develop the local community and to support the chosen strategy going forward.

Motorola Atrix 4G – Simply, The Greatest Smartphone on Earth

0

We do not care what you think. The best smartphone on earth today is Motorola Atrix 4G. It is a very good beast. There is nothing to compare it. It is a specie from another universe. Motorola nailed it and we hail the Mot.

 

From AT&T where we shopped one, these are some comments. We are sending our comments also to the site. There is nothing like the docking station that is so sleek that you just behold the marvel. When will this arrive Nigeria? No one knows because it runs on 4G. Etisalat seems to go ahead of others, it can bring this device to Nigeria sooner than you think. It was the company that got the exclusive 3 months window to introduce Galaxy tab in the nation.

 

 

“This device is awesome!!! With it’s 1 GHz dual core processor, 1 GB of RAM, 16 GB of storage (plus expandable micro SD card slot!), 4” qHD display (which is the perfect size in my opinion), the 5 megapixel shooter, and the unbeliveable thiness makes this one of my favorite Superphones yet! This device can go head-to-head with the iPhone (which I also have), and beat it! The laptop dock, in my opinion, is one of the best inventions since sliced bread! Keep up the good work, this phone is awesome Ma Bell!”

 

“This truly is the most powerful smartphone in the world, for now. The good thing about buying ATRIX 4G is that you’ll more or less be future proof, for a while, actually, for most of 2011. The device has a great 4 inch qHD display (540X960 pixels), that’s nearly the resolution of the iPhone 4 but with more screen real-estate. The display is sharp and colorful. The main selling point, however, is the force behind ATRIX 4G. …”

0

He is young – really young and an achiever. At 21 years, he is a graduate already serving his nation in the NYSC program. A graduate of Babcock University, he is full of ideas and vision. Davia Adamo Jr is one o the creators of Adloopz, an emerging social adverting platform. Tekediacalled it the “most advanced social advertising platform in Nigeria” . And we think the creators are cool and geeky! Yes, they got many aspects nailed down, right.

 

We caught up with David  to  share  insights on their strategies, opportunities, business threats and challenges. People of the world, Tekedia is proud to present David Adamo Jr, a co-founder, Tekedia newest contributor, brainy young man in our Founders Series. The Founders Series interviews owners, founders and CEOs of tech companies.

 

Now, relax and enjoy.

 

Tell Us Your Name and Background

My name is David Adamo Jr., I am a 21 year old software/web developer, an avid music and technology enthusiast. I have a first degree in Computer Science from Babcock University, Ilisan-Remo, Ogun State. I am one of the co-founders of the adloopz.com social advertising platform.

 

I have had quite an adventure with computers and software during the course of my life, and the excitement of this adventure seems to show no signs of waning.

 

Introduce us to Adloopz and its products and services

 

First off, Adloopz was founded and is maintained by a team of young Nigerian software developers comprising myself, Tola Anjorin Jr., Adedayo Adekunle, Efe Amadasun and Shope Johnson.

Adloopz is an internet startup. It provides an advertising platform that emphasizes a social approach to the business of advertising.

 

 

Primarily, Adloopz helps advertisers and ad consumers get the most out of adverts by taking advantage of their presence on other social networks (like Facebook, Twitter, LinkedIn etc.) and the many intricate social connections (loops) created on these social networks by their respective users. This enables advertisers reach a large number of people who share similar interests, thereby increasing the likelihood that advertisers reach their intended audience and convert adverts into sales. By building on the social interconnectedness of people, Adloopz creates an avenue for adverts to be easily shared amongst networks of friends, thus creating a simple yet highly effective referral system.

 

 

On a secondary level, Adloopz.com also aims at providing online equivalents of real-world adverts in such a manner that these adverts are easily reachable and accessible anywhere, anytime on the Internet. In the real world, adverts are often seen and consumed on the go and there might not always be ample time to get the desired necessary details from these adverts. Adverts are delivered to us through billboards, television, radio and a vast array of other media.

 

We might come across billboards while we are in an automobile, or hear an advert on the radio or see a TV ad but the time spent consuming these ads is often dictated by circumstances we cannot control such as advert run time or the time it takes to drive past a billboard. Because of these limitations, we typically are not able to get the most out of these adverts. Adloopz therefore aims to work hand in hand with advertisers to create online equivalents of these real world ads in such a way that they are accessible on the Internet anytime, anywhere and can be downloaded for full consumption by prospective customers and at whatever time they deem convenient.

 

At the surface, Adloopz can also serve as an online marketplace where individuals and businesses can advertise their products and services while having an opportunity for two-way interaction with their prospective clients. In this way, Adloopz provides a system where advertisers are able to create adverts that can self-regenerate and provides advertisers with the ability to measure the impact of ads in real time (reach, likes, referrals, etc.). Essentially, for individuals, we desire to create innovative ways of searching, accessing and sharing adverts.

 

 

Why did you guys create Adloopz and how did you consider that an opportunity?

At Adloopz, we think there is a lot you can do with your friends, and the friends of your friends. This is basically the same kind of enthusiasm you would find in companies like Facebook/Twitter, and this is the same enthusiasm you would find in the Adloopz team. There is no denying the fact that one’s “social graph” is an invaluable tool for dispensing information and for learning about new things. Obviously, the business of advertising is one which knows no end and would definitely continue for as long as people need to sell goods and services to one another, which basically I assume would be forever, except something totally drastic happens to the human race.

 

With advances in technology and the widespread and ever-increasing acceptance of social media as a valuable tool in marketing strategy, the Adloopz team deemed it necessary to create a tool that would leverage technology and social media as a means of enabling advertisers reach out easily to their prospective clients. Simply put, the opportunities that exist as a result of the social interconnectedness of people on the Internet is almost limitless. Interestingly, this social interconnectedness is constantly on the increase and is not likely to stall anytime soon.

 

Could you share with us how you came up with the name? We like it

The name Adloopz defines the core of our service and this is one of the reasons the founding team agreed readily to it. The connectedness of people on social networks and indeed the Internet as a whole can be seen as series of intricate loops. So, the Adloopz team simply took a look at this and said to one another, why don’t we just take advantage of these “loops” and get advertisers to “loop” their “Ads” through already existing social networks?. Then, we kind of felt the letter ‘Z’ looked really cute and much more adorable than the letter ‘S’, so we decided to throw it at the end, and that is how we arrived at “Adloopz”.

 

Specifically, share with us how this company is doing and what your future plans are

Adloopz has been in beta since its launch in March, and has been able to amass quite a number of beta users (on an invite basis), who have given valuable feedback concerning the system. The Adloopz team, based on the valuable feedback we’ve gotten from our users, is working as hard and as smart as it can to implement and refine some essential functionality before the system moves out of beta, and I have to say that is when the fun really starts.

 

So far, the Adloopz team has received kudos for our work in implementing the system. In other words, reception of and comments concerning adloopz.com have been really encouraging. The Adloopz team has quite a number of plans that are urgently being put in the works. Besides the implementation and deployment of some additional functionality that is sure to give our users a reason to keep logging into the adloopz system time and time again, we are also taking our mobile strategy very seriously at the moment. This is obviously because we realize just how important it is to leverage the popularity of mobile phones as a medium through which services on the Internet are consumed.

 

Not least among our immediate plans is the monetization of Adloopz. We have come up with a few ways of achieving this while still providing the highest level of value and satisfaction to all users of adloopz.

 

In the long run, we hope to make adloopz an ubiquitous presence all over the Internet. At this point, I would love to say that having a link to Tekedia’s adloopz profile on tekedia.com would do the blog absolutely no harm. :-)

(all smiled and Editor promised to see how to do that because it will require some coding to make space )

 

How do you plan to scale this business? It has a promise in Nigeria

This is definitely a very important thing that we need to get right. Every business needs to be built to scale. One of the most important steps we are taking to ensure this is making sure that our business procedures and systems are well-documented. This would enable us access and constantly update information concerning our systems in an organized manner as we grow bigger as a business.

 

And of course, there are certain issues peculiar to scaling an internet startup and server infrastructure (hardware and software) forms an important part. As our user base increases, we have to ensure that we are able to adequately sustain the amount of traffic we get. Also, establishing a smooth bug fix and product development pipeline is something we have already worked extensively on.

 

However, at this point I would like to reiterate the fact that in a startup’s life, scaling only becomes an urgent issue after one has gathered a team, decided what they want to build, shipped v1.0 of the product, raised money and demonstrated that people want your product. Until we have achieved all these milestones, scaling is not going to be topmost on our priority list even though I can assure that the Adloopz team is not silly enough to leave if off the list.

 

What are the opportunities for your business line

Adloopz is in the business of advertising. All we have done is take advantage of new advertising trends and existing technology. As I have mentioned earlier, unless something really drastic happens to the human race, there would always be opportunities in advertising as long as people keep on coming up with relevant and innovative ways to reach and appeal to prospective clients.

 

Tell us the challenges your business is facing

Every business faces challenges and finding ways to solve them can be really interesting. I guess that is one vital aspect of being an entrepreneur. Generally, it is not easy doing business in Nigeria as one is faced with challenges, typically emanating from infrastructural problems. This is something most entrepreneurs are familiar with in the Nigerian environment.

 

During the early development stages of adloopz, the team came up with a large number of powerful features that we hoped to deploy in the initial release. After a lot of hard work, we came to the painful realization that the server infrastructure we could afford could not support all the features we had implemented. Therefore, the current version of adloopz.com that you see is actually a trimmed-down version. So, getting the necessary hardware to enable adloopz reach the heights we have planned for it is posing a major challenge.

 

Another hurdle the adloopz team is working hard to cross is generating much needed publicity for the tool we have created. However, we are confident that we are moving in the right direction in this regard.

 

Share with us how you are mitigating those challenges

We’ve gotten quite a number of people who are interested in supporting adloopz. With their support, we are making moves to improve our server infrastructure especially in the area of storage space, so we can fully roll out all the useful features of adloopz we have already implemented. Also, we are making moves to get the word out about Adloopz and Tekedia has already helped us kick start this campaign.

 

Like I’ve said earlier, mitigating our challenges is one thing the adloopz team finds very exciting.

 

Your message to other founders and entrepreneurs

I have a simple message for other founders and entrepreneurs. Create a USEFUL product or service, aim to set a standard and do not settle for mediocrity even if everyone around you seems to be nothing much more than average. It is only this way that your contributions can be fully appreciated by those that derive even the slightest benefits from them.

 

We digress here, you write well and just accepted to become a Tekedia contributor. What will be your first post? Our readers will like to know.

First, I’d like to say I’m honoured to be part of the Tekedia contributing team considering the calibre of people that are already on it. I can only hope I make significant contributions to the growth of Tekedia. I have been having a couple of ideas lately and anyone who has gone through my personal blog at http://www.davidadamojr.com would be able to tell that my blog posts are not solely about programming, software development and technology but span a wide range of issues.

 

I have been planning to revisit the issue of the mediocrity that can be readily seen in the corporate websites of Nigeria’s universities. This mediocrity becomes so glaring when you make the slightest attempt to compare the web presence of Nigerian universities to that of other well-placed universities in other parts of the world. Therefore, there is a possibility that my first post would have something to do with this. However, it is not a 100% certainty. I just might come up with something else. I’m sorry I am not able to give an absolutely definite answer to this question. One thing I can say is that I intend to put in my best.

 

Should you become a LGA chair, Governor or President, tell us how you will make technology to flourish in your country

I am Nigerian and I would never deny that fact. Nigeria is a country with a stupendous amount of individual talent.

 

First and foremost, solving the electricity supply problems we have in Nigeria would go a long way in kickstarting rapid technological development in the country. I have absolutely no doubts about this.

 

Secondly, I believe the key to harnessing the talents bestowed on the citizens of my country lies in our educational system. Unfortunately, the educational sector of Nigeria is not exactly one that can be copied by any entity looking to achieve great things. Therefore, if I happen to be in a position where I can make a quick difference, I would focus on realigning the priorities of our educational system towards an emphasis on hands-on technical adeptness rather than mere knowledge of verbose theories. Special attention needs to be paid to vocational and technical schools (including polytechnics) rather than the current situation where they are being slightly neglected and held in low esteem.

 

I strongly believe that an educational system that lays emphasis on hands-on technical skill and home grown technological innovation would go a long way in helping technology flourish in my country.

 

Thank you

Thank you for having me.
