Face milling cutters commonly require cutter radius compensation?

Solution

WHAT IS CUTTER RADIUS COMPENSATION?

Cutter Radius Compensation also known as CRC, is a function of the CNC controller to automatically shift the tool from the cutter center line to the cutter edge along the programmed cutter path. If it were not for CRC the cutter path locations would have to be calculated to the cutter center line.

advantages of using Cutter Radius Compensation

Three main advantages to using Cutter Radius Compensation (CRC) programming

1) The programmer can use point values that are directly along the cutter path rather than having to calculate the tool center.

2)   During production runs, cutters of different sizes can be used such as         undersize tools when the original size tool is no longer available. It is a simple radius offset value change in the machine control to achieve this. The programming will remain the same.

3)   A program section or operation can be used over and over with different tools to create roughing passes and finish passes. This is done by changing the radius offset value and using multiple offsets.
