Calibration method for numerical control machining-based coordinate system

Abstract

The invention discloses a calibration method for a numerical control machining-based coordinate system. After one-time measurement and machine tool data acquisition, due to mathematical calculation, various types of center points, coordinate values, trajectories and the like are obtained, after positioning coordinate values at any angle of machined products and a product program framework are automatically generated in the system according to a coordinate calculation model, a product coordinate system computational formula, and the size requirements, input according to drawing design, betweenvarious coordinate positions of the machined products, a product program contains all data of a machine tool, a clamping mold and the like, and it is not needed to perform manual input operation or searching and repeated correction of any coordinate system (value) during machine debugging; and finally, a CNC technician transmits the product program into the machine tool, tool setting machining ofa tool is performed, then a first qualified product of the products can be obtained, and therefore fast machine debugging is achieved, and the first product being the qualified product is a target.

Description

technical field [0001] The invention relates to a calibration method of a numerically controlled machining base coordinate system. Background technique [0002] As the sanitary hardware industry's "small batch, multiple models, short delivery time" personalized and order-based production mode has become more and more obvious, product processing and production changes (CNC adjustment) have become very frequent. Furthermore, factors such as labor cost and equipment utilization rate of labor-intensive enterprises have become one of the main problems of enterprise management. In the end, only the implementation of "lean production", "quick production change" and "smart manufacturing" is the magic weapon for the upgrading and transformation of traditional labor-intensive enterprises in the future. [0003] In today's numerical control system, the function of macro program is very powerful, and the use of macro program to make some canned cycles has been widely used. G54-G59 are...
