Control method, system and device for cutting speed of machining machine table

Abstract

The invention discloses a control method, system and device for cutting speed of a machining machine table. By means of the steps of controlling form prereading of machining programs, judging machining paths and generating arc path speed, according to the arc speed limiting ratio input by a user and a machining program control form to be executed, the actual machining speed of executing the machining program control form is obtained, and a signal is transmitted to the machining machine table to control a cutter on the machining machine table to work at the actual machining speed. By means of the method and the system, the user can dynamically adjust and change the operation speed of the arc machining path under different workpiece machining conditions without particularly changing machining speed set previously through complex procedures like calculation and any machining operation habits, the problem that as the radius of the cutter is too large, arc machining operates too slow, and machining efficiency is low is avoided, the machining time can be effectively saved, and production cost can be effectively reduced.

Description

Technical field [0001] The invention relates to a cutting speed control method, in particular to a control method, a control system and a control device for the cutting speed of a processing machine. Background technique [0002] In the machine tool manufacturing industry, in order to achieve the purpose of enhancing industrial competitiveness, high-efficiency manufacturing technology is a key indicator, and the speed control of manufacturing processing is an extremely important link. However, in this link, in order to match the load range that the machine tool mechanism can withstand, there must be an ideal upper limit for the processing and manufacturing speed to prevent excessive mechanism jitter, which affects the service life of the machine tool and the quality of processing and production. However, there is a certain degree of difficulty in drawing up the upper limit of this processing speed. It is usually necessary to set an appropriate value according to the rule of thumb...

Problems solved by technology

[0005] However, the factors that affect the processing quality of the workpiece, in addition to the cutting speed of the cutting tool and the surface of the workpiece, the material properties of the workpiece, the temperature and humidity of the machine working environment, the stability of the machine tool assembly mechanism, and the machining deviation caused by the centrifugal force caused by the spindle speed Various factors, such as shifting, may affect the processing quality of the finished workpiece.

In other words, the cutting speed between the cutting tool and the surface of the workpiece is not the only factor that determines the quality of the finished product. Therefore, in the needs of some industries (such as: grinding machines), it is hoped that the angular speed can be appropriately accelerated and the maximum linear speed can be maintained. In the past, it could only be achieved by modifying the processing program to increase its maximum feed rate limit

However, according to this method, the feed rate limit of the processing program must be adjusted one by one for different processing programs corresponding to different processed products or when using different tools to change the tool radius. Under the industrial characteristics of high-speed production, this This move will increase personnel costs and seriously drag down production efficiency, which may lead to a decline in corporate income
