Course Description

One of the most exciting aspects of pursuing a career in the CNC industry is the job outlook. Currently, there is a skills gap, which has led to a high demand for machinists and programmers. “So much is made with CNC machines, and there are so many industries you can get into”.

The manufacturing industry relies heavily on computer-numerical control (CNC) machining, including operations that once used engineer-operated equipment like routers, shaping machines, vertical millers and centre lathes. The many CNC machine advantages mean operator-required equipment has in some cases been replaced entirely. Manufacturers of many types across many industries choose the advantages of CNC machining for their fabrication and manufacturing applications. It provides efficient, expedient and precise production capacity ideal for creating large quantities of items.

This course is intended for learners from a vast range - Mechanical engineering, Manufacturing engineering, Industrial engineering, Machinists, Hobbyists & the list goes on. Even working professionals who wants to brush up there knowledge will get benefited. 

The course will start with a basic introduction about Numerical control, its history & how it had been introduced in the modern industry. Then we will discuss about various types of popular CNC machines in the industry. And finally we will learn about the basics of CNC programming which will include programming format explaining different types of codes as such G code, M code, S,D,F and many more. Then we will get to know the most simplest & precise way of writing a CNC program with complete coding. Then we will discuss about two popular approach in CNC programming that is absolute & incremental mode. And finally we will write a complete program involving everything we have learned & even more.
