Do you have what it takes to be a TOP-GUN machinist?

Posted by Bert Maes on December 2, 2009

Computer numerical control (CNC) machining makes all manufacturing processes much easier by automating and speeding up the production of the everyday objects we all know.

What does it take to be a CNC specialist?

  • Above all; this is a job for creative minds – creators and makers. People that are willing to produce original, surprising and unusual ideas.
  • Highly creative people tend to be independent, nonconformist and unconventional. They are likely to have wide interests, greater openness to new experiences and a more cognitive flexibility and risk-taking boldness.
  • CNC machining is not as easy as you might think. You will have to acquire considerable expertise. It is often said  that in any chosen domain it takes 10 years of training and effort to fully master the necessary knowledge and skills to produce a work of genius. You can find many examples of genius CNC manufacturing on
  • Working with CNC machines means that you will be dealing with a lot of computer work. You have to be very familiar with computer operations.
  • You have to have knowledge about blueprint reading to know what to program the machine to do. This is because basic design concepts and construction is hinged heavily on blueprints.
  • CAD, blueprint & product specifications must be translated through CAM computer software into a machine-readable format.
  • CNC machines only understand commands in a specific programming language, so you will have to learn so called “G-codes” in depth.
  • You will have to be very familiar with machining operations: Which machine tools are for which job? How fast can the machine work? What is the rate of feed for the machine? What is the depth of the cut needed for the operation? How do I measure that? What are the right tools and cutting sequences, with efficiency and safety in mind? How should I install the most solid workpiece clamping and positioning solution? What is the best coolant and lubrication mix and how should I regulate and adjust the flow to material needs?
  • You must be able to interpret data in the program output stack, comparing test results with design specifications
  • In case of any glitch, you will need to learn to perform programming edits and restructure the program quickly.
  • You will have to control and prevent damage to tools, materials, or machinery during the production cycle.
  • Of course cleaning and removing any waste material in a safe manner is part of the job.

Last, but not least: salaries are very negotiable: companies take care of their CNC specialists as there is always a shortage of skilled enough people to take hold of the position. In Europe, people on manufacturing earn 9% more than others…

The benefits are solid. Think about this career. Check and for the best CNC schools.

[Video] How quality knives are actually produced

Posted by Bert Maes on November 16, 2009

Kevin Wilkins is one of the best custom-made knife makers in the world.

gd7_09He shows on his website that the creation of these everyday useful objects in the most effective and efficient way all comes down to four (4) things:

  1. Designing a computer CAD/CAM blue print of the object you want to make.
  2. Selecting the right metal, aluminium or other material.
  3. Learning how to program and handle precision cutting CNC machines.
  4. And lots of passion and creativity.
