Introduction

Machining is one of the most fundamental manufacturing processes used to shape materials into precise components.

It plays a critical role in industries such as automotive, aerospace, medical, and industrial equipment manufacturing. By removing material from a workpiece using cutting tools, machining enables high-precision parts to be produced efficiently.

Understanding machining is essential for:

• Learning manufacturing fundamentals
• Optimizing CNC turning and milling processes
• Improving product quality and productivity

Machining is a manufacturing process in which material is removed from a workpiece using cutting tools to achieve a desired shape, size, and surface finish.

The process typically involves:

• Controlled cutting motion
• Machine tools such as lathes and mills
• Precise adjustment of cutting parameters

Machining is widely used for producing both simple and highly complex components.
