Abstract

The invention relates to an application method of numerical control macroprograms in a parallel machine tool. The application method comprises the following steps of S1, inputting data of to-be-machined parts into CAM software, and utilizing the CAM software for processing to obtain a machining path; S2, converting the machining path into a G code according an after-processing program; S3, constructing the parallel machine tool inverse kinematics macroprogram; S4, constructing the parallel machine tool forward kinematics macroprogram; S5, utilizing the G code for calling the parallel machine tool kinematics inverse macroprogram and the parallel machine tool forward kinematics macroprogram separately to obtain a machining code; S6, inputting the obtained machining code into a numerical control system of the parallel machine tool, and controlling the parallel machine tool for machining the to-be-machined parts. According to the application method, the macroprograms are utilized for reasonable mathematical transformation, application of a traditional numerical control machine tool controller to the parallel machine tool is effectively expanded, same principles can be combined with multiple controllers, the economic cost is effectively reduced, and the application method has a wide industrial application prospect.

Description

technical field [0001] The invention relates to an application method using a numerical control macro program in a parallel machine tool. Background technique [0002] The traditional tandem structure machine tool is a machine tool with simple mathematics and complex structure; in contrast, the parallel structure machine tool is simple in structure but complex in mathematics, and the movement of the entire platform involves quite a large mathematical operation, so the parallel machine tool is a kind of knowledge-intensive type machine tool. This kind of machine tool completely breaks the concept of traditional machine tool structure, abandons the tool guide method of fixed guide rail, and adopts multi-bar parallel mechanism drive, which greatly improves the rigidity of the machine tool, and greatly improves the precision and quality of machining. In addition, due to the increase of its feed speed, high-speed and ultra-high-speed machining are easier to achieve. Because thi...
