Characteristics Analysis of Cutting Quality on Semi-Flexible Hollow Rectangular Structures of an Insulating Paper for Mass-Production of Slot Liner in EV Motors

The method of acquisition, analyzation and evaluation of cutting characteristics was developed on a hollow rectangular tube-like structure made of an electrical insulating paper (so called the slot liner in the motors of electric vehicles). The slot liner was cut by a steel disk blade. The cutting force was measured by the dynamometer, to evaluate the specific energy of the cutting: Cp, and the ratio of tangential and normal component of the...
