Why is chip removal crucial during CNC machining?

Chip removal is crucial during CNC machining primarily to prevent interference with the tool. During the cutting process, material is removed from the workpiece in the form of chips. If these chips are not effectively removed, they can accumulate around the cutting tool and interfere with its operation. This interference can lead to several issues, including tool dulling, inaccurate machining, or tool breakage, all of which negatively affect the quality of the finished part.

Moreover, the accumulation of chips can also impede coolant flow which is important for maintaining optimal cutting temperatures and prolonging tool life. Therefore, effective chip removal helps maintain consistent machining conditions, ultimately ensuring precision and efficiency throughout the manufacturing process. This focus not only preserves the integrity of both the tool and the workpiece but also enhances overall production reliability and productivity.
