Modular polar coordinate cutting method with variable functions and digital controlled cutting apparatus

Abstract

A modular polar-coordinate cutting method able to realize function exchange features that the cutting machine can be splitted into modules as required, all modules are mutually connected in polar coordinate mode, the module connected to cutting head can rotate, and exchanging relative module can change its function. A numeral controlled cutting machine based on said method features that its straight moving module has a moving platform connected to polaxis module, its pole radius module is connected to polaxis module and can revolve around it, the control-display module and cutting head module are fixed to pole radius module, and the cutting head module can move in axis direction of pole radius module.

AI Technical Summary

Problems solved by technology

[0003] The existing CNC cutting machine adopts the form of rectangular coordinates, and its structure is divided into two types: cantilever type and gantry type. The range is fixed, the cutting range is X×Y

(X and Y are the lengths of the longitudinal guide rail and the transverse guide rail respectively), which is difficult to meet the requirements of some special processing workpieces; ②The function of the product is relatively single: the functions of the existing cutting machines are usually flame cutting, plasma cutting, water jet cutting or One of the types of laser cutting, it does not have a variety of cutting functions, nor does it have the function of replacing the cutting head; ③ there are disadvantages in cutting certain characteristic parts: the existing cutting machine uses the principle of interpolation when cutting arcs For cutting, the cutting of the arc is fitted with many small straight lines

Therefore, in arc cutting, the cutting speed is slow, the cutting quality is poor, and large shape errors often occur
