Frequent question: What is the need for cutter radius compensation How do you decide the use of G41 and G42?

What is the need for cutter radius compensation?

Cutter radius compensation compensates for the radius of a cutting tool by causing the controller to maintain a constant offset that is perpendicular to the programmed path in a two-dimensional plane. You can use this feature to compensate for the diameter of a cutting tool or the width of a laser.

What is cutter radius compensation explain with example?

Cutter Radius Compensation (CRC) is used in a program to allow the operator to alter the path of a cutter. EXAMPLE: After cutting the part with path 1, the operator measured the part and determined that the part was undersized.

What does G41 mean?

List of G-codes commonly found on FANUC and similarly designed controls for milling and turning

Code Description Turning ( T )
G41 Tool radius compensation left T
G42 Tool radius compensation right T
G43 Tool height offset compensation negative
G44 Tool height offset compensation positive

How do I use my G40 G41 G42?

Cutter Compensation Cancellation (G40)

Function G40 is used to cancel cutter radius compensation initiated by G41 or G42. It should be programmed after the cut using the compensation is completed by moving away from the finished part in a linear (G01) or rapid traverse (G00) move by at least the radius of the tool.

What are two benefits of cutter radius or tool diameter compensation?

It lets a manual programmer ignore cutter size when calculating coordinates for the program, it allows the setup person to choose from a range of cutter sizes, and it allows for easy trial machining and workpiece sizing during setup and the subsequent production run.
