Problems solved by technology

[0003] In the prior art, the programs generated by computer automatic programming are cumbersome and lengthy, and basically occupy a large amount of storage space. However, the memory space of general CNC machine tools is small and cannot be completely stored. For example, online processing through DNC may cause intermittent phenomena, which directly affect Processing effect; In addition, computer automatic programming must go through four parts, the process is complex, the program is lengthy, the readability and modification are poor, once the breakpoint phenomenon or size deviation occurs during the processing process, it has to be reprogrammed for post-processing to generate the program and transferred to the CNC machine

Embodiment Construction

[0050] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0051] Such as figure 1 As shown, a NC programming method for conic surfaces with equal-width steps includes the following steps:

[0052] ①Setting the programming file: write the surface image, the function of the cutting method and the parameter line equation into the programming file, and the surface image is the surface image of three equal-width steps;

[0053] ②Decomposition, extraction and acquisition: Decompose the surface image, extract the surface equation, obtain the surface curve circumferential angle equation and the lateral step, and the lateral step is the distance between the tool and the tangent line of the circumferential angle of the surface curve;

[0054] ③ Parametric surface curve circumferential angle equation: Use the parametric line equation and the surface curve circumferential angle equation to form an e...

Abstract

The invention provides a numerical control programming method of an equal-width stepped conic curved surface. The method comprises the steps of setting a programming file, carrying out decomposition,extraction and acquisition, parameterizing a curved surface curve circumferential angle equation, calculating a line space, obtaining a valid line segment length value, and completing the processing.According to the method, a numerical control machine tool secondary development programming environment is used to carry out manual programming, a cutter trajectory is calculated through a parameter line approximation method and a combination of multiple cycles, a cutter moves along a parameter line of each axis of the curved surface, a main program and a sub program are compiled, and the numerical control programming processing is carried out through a method of calling the sub program through the main problem. The method has the characteristics of a simple calculation method and a fast calculation speed. The program is clear, concise and easy to understand and has good readability and modification, the program is flexible and convenient to modify and edit, the program has high reliability and a small capacity and can be completely stored in a numerical control system, processing interruptions are avoided, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to a numerical control programming method for equal-width stepped conical surfaces, belonging to the technical field of numerical control programming. Background technique [0002] With the rapid development of industrial technology, various advanced CNC machine tools have been widely used in modern manufacturing. CNC machine tools need to be controlled by programs when processing parts. As CAD / CAM functions become more and more powerful, computer automatic programming technology is more and more widely used. The main process is CAD feature modeling, automatic generation of tool paths, NC simulation and post-processing. Its main advantage is high efficiency in programming, especially when processing complex parts, and it can greatly reduce the calculation workload of the operator. Most modern CNC machine tools provide a secondary development programming environment, although It is an inevitable trend for computer automatic progra...
