Abstract

This invention relates to machine tool testing field, providing a precision analyzing method for machine too, a virtual test system and equipment, the method comprises following steps: establishing a physical test system according to machine tool structure and testing to obtain temperature field and machine tool precision test result via the physical test system; establishing a virtual test system according to parameters of the physical test system and obtained temperature field test result, then calibrating the virtual test system according to machine tool precision test result obtained by the physical test system. Upon establishing and calibrating virtual test system according to test result from the physical test system established in accordance with the machine tool structure, this invention realize a machine tool precision analyzing method in order to enhancing machine tool precision, processing quality and efficiency, and simultaneously reduce design period of new product and save research and development cost.

Description

technical field [0001] The invention belongs to the field of machine tool testing, and in particular relates to a machine tool precision analysis method, a virtual detection system and equipment. Background technique [0002] Considering the requirements of high precision and high efficiency of the machine tool, for example, the precision of the machine tool needs to be controlled within a few microns, and the efficiency must be kept above 300 holes / minute. The temperature field distribution of the whole machine and the deformation caused by motor, motion friction and other factors will affect the accuracy of the machine tool. At present, methods such as grating ruler and laser interferometer are widely used in the industry to compensate the positioning accuracy of the machine. The advantages are simple, fast and cost-saving, and the compensation results can basically meet the design requirements. But there are also some problems at the same time, for example: the compensat...
