The problem is that one machine will not activate tool compensation, and the other works fine. I have a bunch of flanged bushing shaped parts, of varying sizes, to produce, and have written a parametric program, that includes a couple of G71 roughing cycles for the project. Things are up and running on the lathe with the MSG-803 controller, however, when I transferred the exact program to the lathe with the MSG-805 controller, tool nose comp is apparently not working??? The obvious things like tool nose radius, and tool tip designation (i.e. 3 for the turning tool / 2 for the boring bar) have been entered into the machine that is not functioning properly. I don't know what else to check. As a matter of fact, the programming manuals for each machine are virtually the same, in regard to automatic tool nose radius offset. I may be wrong, but I'm inclined to think the problem is something other than the program. It is probably something really simple and basic that I'm overlooking. Any help would be much appreciated.
