Embodiment Construction

[0161] The present application takes a five-axis linkage and parallel kinematic machine (PKM) as a specific embodiment to describe the technical solution of the present application in detail.

[0162] In the technical background, the present application has pointed out that the generation of the tool path curve is the most extensively researched content in the existing CNC system. The application also pointed out that no matter how complicated the mathematical calculation is, it is not a problem to generate the tool path curve for the complex motion relationship in the mechanism. The difficulty is that the feed amount of the relevant coordinate axes must be interpolated in real time in a very short time. For five-axis linkage and parallel machine tools, all the technical bottlenecks of the existing CNC system essentially originate from this.

[0163] The coordinate axes of the five-axis linkage CNC machine tool include three translation axes and two rotation axes, and the five...

Abstract

The invention provides a machining file planning system and a machining file generating method and particularly provides a simple and reliable tool path curve generating method and a real-time control method for parallel mechanisms (including parallel machine tools and parallel robots), five-axis computer numerical control machine tools and the other complicated computer numerical control devices. The high-accuracy planning is performed on a tool path curve so as to improve machining accuracy and motion stability of a coordinate axis, a universal G-code program is replaced by a machining file, G-code programming is omitted, machining program compiling is similar to short message editing through word, 'computer numerical control is just like mobile phone playing, and programming is similar to short message editing', the interpolation era is thoroughly over, and the technical access threshold and the required cost of a CNC system are remarkably reduced.

Description

technical field [0001] The application belongs to the field of advanced manufacturing, and specifically relates to a processing file planning system and a processing file generation method in a computer numerical control system (Computer Numerical Control system, CNC system). technical background [0002] The basic principle of the existing CNC system is that in an interpolation cycle, for different tool path curves, such as straight line or arc, the real-time operating system calls the linear interpolation module or the circular interpolation module, according to the feed speed, Use the linear interpolation algorithm or circular interpolation algorithm to calculate the feed amount of the relevant coordinate axes in the interpolation cycle, send it to the relevant servo driver, and drive the relevant coordinate axes to generate a composite displacement. Following the interpolation cycle, it goes round and round to complete the processing of the workpiece. [0003] This appl...
