Abstract
A diamond cutting tool tip temperature in a micro cutting of zirconia ceramics was measured by a two color pyrometer with an optical fiber. A quadrangular pyramidal, single crystal diamond was used as a cutting tool. The tool has a small hole and the optical fiber was inserted into the hole. During the cutting, the fiber accepts the infrared rays radiated from the tool-chip interface and transmitted through the cutting tool. The relationship between the types of cutting grooves and cutting forces and temperature was investigated.
