> Hi Gene, In short tool comp works like a charm but the toughest part for me has always been getting into it. I think the approach needs to bend a bit; even a thou will do so that you are cutting an outside corner in entry. Try starting about a tool dia away from your part. Like you said, mike the tool and enter that into the tool table.
When you really need a part correct consider using G2(3) X Y I J, where I and J are the X and Y offsets (distances) from the end point of the path to the center of the circle. All of this assumes you are working in the G17 i.e. X Y plane. Your program gets to use the actual points on the part and cutter comp offsets the tool the correct amount. EMC was written with a lot of forethought and planning and will work with either tool diameter or with negative (only) corrections to the tool dia. Synergy produces code that uses 0.000 in the tool table for nominal diameters and then one corrects by entering the negative corrections for adjusting the part relative to the tool which is good for production. With EMC I've often roughed the part with a tool at 0.503" and then changed the tool dia to 0.500 for the finish cut. Really handy. Probably TMI but hope this helps.
