The softer material should be used on the main focus of hand to reduce vibration.
So the antiskid and reduction of vibration is the design point for the electric drill hand (shown in Fig.18). 4.4 Extraction The material of the electric drill hand is plastic, and its wall thickness is 2mm.

Where iK , 1iC , 2iC , 3iC ( , ,i x y z= ) is constant, their values depend on workpiece material, tool

The formula can be used to anticipate milling forces before high-speed milling stainless steel 316 or other material hardness around HRA50, so as to optimize cutting data.
