WebHow to Calculate the Feed per Tooth ? Option 1: Divide the linear distance traveled by a milling cutter during one full spindle rotation ( Feed per Revolution) by the number of cutter’s teeth. Option 2: Multiply the recommended Chip Load by the Chip Thinning Factor.

WebAug 1, 2024 · Constant Chip Thickness is the Key The key to being able to cut faster and improve tool life is to keep a constant force load on the cutter. This reduces the shocks and vibration that occur when material engagement changes abruptly, for example, when a tool hits the corner of a pocket. WebOct 5, 2024 · As a general rule, chip thickness must be at least as large as the radius of the cutting edge. For example, a 60 μm edge radius requires feed be adjusted to produce chip thickness of at least 60 μm. At a feed rate that is too low, the edge will rub and fail to cut the workpiece material.
