RE: [CAD_CAM_EDM_DRO] Tool radius compensation

I would say it depends upon the individual or the policy of the company for
which one works. Almost all controllers have radius compensation so it is
easier to compensate for sharpening of tooling, etc. On the other hand, most
CAM software also has radius compensation, as you state, so as long as the
actual tool used is the same radius as the one used in the CAM software it will
work. Most of the companies I serviced where they had several CNC machines
operating with multiple operators used the compensation in the CAM software,
that way the operator isn't required to remember to set up the radius
compensation in the controller. Since most machines are connected to the
company's local area network, or even a wide area network, it is much easier to
just download a new part program. That also helps remove at least one level of
human error.



Personally, I use the compensation in the CAM software, just one less thing to
worry about in the controller.



Hope this helps some.

Subject: [CAD_CAM_EDM_DRO] Tool radius compensation





When using tool compensation with CAM it is possible to either to get
the CAM to create tool paths that follow the part outline, making the
control compensate for the whole tool radius or follow the tool tool
center line with the control just compensating for wear. Which is more
commonly used?
