Abstract

A granite step-pitch gage measuring device is composed of the granite step-pitch gage and the displacement sensor. Because of the accuracy of the granite step-pitch gage and the sensor, it can be used in the workshop to measure the error of the machine axis to a series discrete point. So it can reach the evaluation of the machine accuracy and the compensation of the pitch error. The invention can resist the wearing, acid, alkali, rust and cost little, especially it has the high measurement accuracy.

Description

technical field

[0001] The invention belongs to a device for measuring the single-axis axial positioning error of a numerical control device, in particular to a measuring device for a granite step gauge. Background technique

[0002] For the measurement and evaluation of the position accuracy of CNC machine tools, the international standard IS0230-2: 1997 (test code for machine tools-part 2: Determination of accuracy and repeatability of positioning numerically controlled axes) and the national standard GB10931-89 both recommend the use of laser interferometers (Laser Interferometer ). The laser interferometer has high measurement accuracy, which can generally reach 0.1 μm. However, the laser interferometer takes a long time to measure, requires special personnel to operate, and has high environmental requirements. It is generally not suitable for use in a workshop environment, and it is expensive. Therefore, it is not an ideal measuring device. At present, it is also rec...
