Mill Load Rate

Chip Load

2021-5-2 · Chip load is usually between 0.001" and 0.010", with exact maximum chipload determined by end mill manufacturers based on the end mill and stock material characteristics, like surface speed. Most prototyping work on any material can be done well with a chipload of 0.005" for roughing passes and 0.002" for finishing passes. Even the sharpest ...Tutorial - Feeds and Speed - MekanikaChip load is expressed in mm/tooth and can be found using the following equation: Feedrate = N x Chipload x Rpm. where N is the number of flutes of the end mill and Rpm is the rotational speed of the spindle. Let''s illustrate this concept and imagine you want to cut plywood with a 6mm 2-flutes end mill. In our case, the recommended chip load ...
