CIMCO Filter drastically reduces your machining time and file size by converting multiple linear moves into arc moves, creating a much smoother toolpath. The file size can be reduced by more than 50% without any loss of accuracy with respect to the original surface.
Most filtering software will simply follow the tools path. This can cause problems in zig-zag toolpaths, as the filtering causes the tool to be close to the lower tolerance limit in one direction, and close to the upper tolerance in the other direction. As can be seen in the left picture below, this causes large scallops, and a poor surface finish.
CIMCO Filter eliminates this problem by detecting the zig-zag nature of the toolpath and performing the filtering calculation in the same direction on all passes. As can be seen in the right picture below, this gives a much smoother surface. Or you can get the same surface quality as with most other filtering software, with nearly half as many passes.
