Other Recommendations

Climb milling is generally best for finish milling because the cutter takes the thick part of the chip when it enters the cut. In conventional milling, the chip thickness starts at zero, causing rubbing or burnishing before the chip can reach its full thickness.  Ingersoll Cutting Tools logoPressure and heat build up at the finished surface. The thin section will then weld to the cutting edge and be carried around to scratch the surface.
Avoid cutting with the full diameter of the tool. This also results in zero chip thickness at the point of cutting edge entry just as in conventional milling. Two-thirds of the tool diameter is best when finish milling. It is also important to cut in the same direction when consecutive passes are required.
Finish milling depths are usually light (.003″-.010″). Greater Advance Per Tooth (APT) can be used, sometimes as high as .125″. Finish milling cutters should be less dense than rough or semi-finish cutters, although high-density cutters may be required for some high production cast iron applications.
