Technical information – milling Technical information Solid carbide mills HSC strategy A It's important to use the right strategy. When programming make sure the width of cut is kept. The width of cut is usually not higher than 15 %. Regarding the depth of cut, the total length of the cutting edge can be used. Turning hmax fz = hmax fz B d d Milling ae ae ae < d/2 hmax < fz ae ≥ d/2 hmax = fz ae a hmax = 2fz (1− e ) d d When changing the width of cut the cutting data needs to be adjusted. As calculatory size applies a chip thickness from approx. 0.15 –0.2 mm on basis of the usual steel types.
