Cutter compensation for groove-turning applications

Recommended Posts

Hello community,

I am looking for any suggestions or feedback on groove-turning applications and cutter compensation. These applications use multi-purpose parting tools that are also designed for OD profiling, and even facing. Iscar and Thinbit are popular among companies who make these tools.

Here's an example of a Thinbit tool in action:

I realize that many people would hand program something like this, but that is not an option - we have to use Mastercam. A major point of confusion has been the cutter-compensation. Since we are using both sides of the tool, we are essentially toggling between G41 and G42, and also using at least two quadrants: 3 and 4. It seems that generating a tool-path on Mastercam requires forming a consensus on how the tool will be setup at the controller (Fanuc).

Is anyone familiar with these operations?

How did you setup your offsets at the controller?

Did your toolpath toggle between G41 and G42?

Did you have to enter the quadrants in your offsets (usually a T value)?

Simce these operations use multiple quadrants, and there is only one 'T' value for each offset, did you have to use multiple offsets?

Thank you so much
