Coordinate system for automatically compensating temperature deformation and tool shape offset

Abstract

The invention provides a coordinate system for automatically compensating temperature deformation and tool shape bias. The system comprises a coordinate system management unit, a coordinate system original point offset file analyzing unit and interfaces for realizing some functions together with other units, wherein the coordinate system management unit comprises a tool point coordinate system establishing module and a tool point correction coordinate system establishing module. The coordinate system for automatically compensating the temperature deformation and the tool shape offset has the beneficial effects that a tool point coordinate system is established through the tool point coordinate system establishing module, so that an NC (Numerical Control) machining program is compiled by only programming a position of a tool position, so as to replace a programming mode of programming a movement control point (a special position of an end part of a grinding spindle or a turning head) and programming a tool shape offset compensation code in the prior art. The tool point position offset compensation work by a user through programming is saved. Furthermore, the system can realize real-time compensation, so as to ensure the machining accuracy.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, and more specifically relates to a coordinate system for automatically compensating temperature deformation and tool shape deviation. Background technique [0002] The workpiece processing of CNC machine tools is generally completed by program control, so the determination and use of coordinate systems and coordinates are very important. In order to explain the position of the particle, the speed of motion, and the direction of motion, etc., a frame of reference must be selected. In the frame of reference, in order to determine the position of a particle in space, an ordered set of data is selected according to a prescribed method to identify the position of the particle. These are called "coordinates". The method of specifying coordinates in a problem is the coordinate system used by the problem. If the particle moves along a straight line, in order to quantitatively describe the...
