Introduction
During the operation of a machine tool, the material characteristics of the processed workpiece, the
addition of the cutting fluid, and other practical processing situations may directly affect the
processing quality.

Abstract.
Introduction Silicon carbide (SiC) has been expected as a material for high power, high temperature, high frequency and low-loss devices.
Journal Title and Volume Number (to be inserted by the publisher) 3 In the case of a convex bulk crystal, a different of impurity density can be generated in a wafer, since a convex bulk crystal may have large difference in the growth rate between the central region and the edge region.

Measuring Principle
The principle of the angle sensor is based on the internal reflectivity change of incident light when the
angle of incidence is near the critical angle of the higher refractive index material and is based on the
differential measuring method (see Fig.2).

Introduction 4H-SiC's superior material properties enable thinner, more heavily doped drift layers that can withstand high breakdown voltages, resulting in lower specific on-resistance (Ron,sp) and making unipolar devices more viable compared to silicon-based counterparts.
