CNC machining is a subtractive manufacturing process that involves removing part of a workpiece using instructions from a CAD model to make a product. The CNC machine removes parts of the workpiece by machining operations such as turning, drilling, or milling, according to codes (g-code and m-code) obtained from the CAD model and containing instructions on machining parameters.
FAQs
What are M-code and G-code?
On the one hand, G-codes are a set of codes that instruct a CNC machine on how to move. On the other hand, M-code carries out the machine’s non-cutting operations.
What are the main challenges in CNC machining?
Customization is not particularly easy with CNC machining. Machinists must modify the CAD files in the initial step to make minor adjustments to the finished products. Also, technological improvement allows only a skilled operator to write the programs.
What industries are CNC machining used in?
CNC machining has applications in many manufacturing industries. Common industries adopting the manufacturing process include automotive, aerospace, military, defense, marine, and medical.
