I haven't had much luck getting answers over on the Bobcad forum so I thought I would try here. There seems to be a fair amount of Bobcad Usage here. Anyone like it? I am having problems getting a part to pass quality using Z-Level Rough and Z-Level Finish. This is what I am seeing for problems on the most recent part. I have a solid part that was imported into Bobcad v24 from an IGES file. I created a z-level rough using the solid as the geometry. I have left an xyz allowance of .020 with a .100 depth of cut and a .200 stepover using a .500 endmill. The roughing operation is leaving over .030 in the z direction on some surfaces but not all. I expected the Z-Level finish with 0 xyz allowance to clean everything up, but the final depth is not being cleaned on all surfaces. Are the Z-Level Rough and Z-Level finish operations supposed to be aware of each other? I often find myself cutting air and don’t see any rhythm or reason to the paths. How do the depth of cut and stepover in the roughing operation and depth of cut in the Z-level finish affect the final result? For example if there is not enough material left to do a full step over or full depth cut in the roughing operation is that material left for the finish operation? I don’t quite understand the logic of these operations. I assumed that regardless of cut and step inputs the program would take the part to the allowance input.
At $55/stock, we are tired of making parts that don't pass quality. Any thoughts would be very much appreciated. I can attach my file if anyone thinks that would help?
Thanks much.
