Abstract

The invention provides a diamond tool setting method. By combining LVDT and the tool rectifying method, damages of tools due to excessively cutting in the traditional tool rectifying method or since the tool is higher than the spindle center are avoided. The method includes setting two circles with numerical values Phi 1 and Phi 2 through a processing program, measuring the diameter numerical values as Psi 1 and Psi 2, establishing equations according to geometric relations, figuring out the equations, and obtaining an adjusting numerical value of the tool in the Y direction; setting a circle with the diameter of Phi 3 on the end face of a workpiece through the processing program, measuring the accurate numerical value of the diameter through a measuring microscope as Psi 3, and allowing an adjusting numerical value of the tool in the X direction to be (Phi 3-Psi 3)/2 or (Psi 3-Phi 3)/2. Accurate diamond tool setting is realized.
