early version fusion control on vertical milling machine eia/iso tool data problems. Part is programmed from part center. trying to use tool data for wear offsets using 1/2 end mill .5 end mill goes back in forth on a 1.0 wide slot putting .5 in tool data. Put zero in tool data cuts 1.0 great. Problem is cannot put a negative number in data to account for wear. Put parameters back so using D in program with cutter comp. turned on using the D and tool offset page it does move properly on slots and width traveling in x direction. Using a different tool using cutter comp and D tool does not move or read offset. Tool path direction is + to - in y direction with a four radius part, shape is right just need to make bigger. What could be wrong and a easy version of how to achieve solution using tool offset or tool data new to eia program in mazak. Program was wrote using gibbs software.
