A multi-wire cutting machine table feeding method based on stepless speed change

Abstract

The invention provides a multi-wire cutting machine workbench feeding method based on stepless speed change. The real-time feeding speed of a workbench is infinitely variable, and the speeds are the same at the portions where the contact areas of cutting wires and a round material are the same. The method includes the specific steps that workbench feeding is driven through a servo motor, the workbench feeding position is fed back according to data of a servo motor encoder, the workbench feeding position which is fed back is transmitted to a programmable logic controller, when the round material is cut, stepless speed change workbench feeding technical parameters are input into a multi-wire cutting machine touch screen, and the real-time feeding speed of the workbench is calculated througha workbench stepless speed change control algorithm in the programmable logic controller. By means of the multi-wire cutting machine workbench feeding method based on stepless speed change, the manualcalculation process of a cutting technology can be omitted, the stability and accuracy of cutting parameters are ensured, and the surface quality of cut products can be improved.

Description

technical field [0001] The invention relates to a multi-wire cutting machine table feeding method based on stepless speed change. Background technique [0002] At present, the feed of the worktable of the known multi-wire cutting machine adopts a continuous and multi-stage speed control method. The change of each speed is abrupt, and the speed change is realized in a very short period of time, and the workbench is in the same section. The feed speed is uniform, and the segmented position and speed of the workbench need to be calculated manually and input through human-computer interaction equipment. The accuracy of the process parameters varies from person to person, and the accuracy is not good. [0003] When the multi-wire cutting machine table is continuously fed at multiple speeds, when the cutting surface is circular, the contact area between the cutting material and the cutting line changes continuously with the feeding of the table position, resulting in The force on...

[0002] At present, the feed of the worktable of the known multi-wire cutting machine adopts a continuous and multi-stage speed control method. The change of each speed is abrupt, and the speed change is realized in a very short period of time, and the workbench is in the same section. The feed speed is uniform, and the segmented position and speed of the workbench need to be calculated manually and input through human-computer interaction equipment. The accuracy of the process parameters varies from person to person, and the accuracy is not good.

[0003] When the multi-wire cutting machine table is continuously fed at multiple speeds, when the cutting surface is circular, the contact area between the cutting material and the cutting line changes continuously with the feeding of the table position, resulting in The force on the cutting line is not uniform, so that the bending degree of the cutting line is inconsistent, and the position is shifted, resulting in uneven line marks on the cutting surface, reducing the flatness of the cutting product, and increasing the workload and difficulty of the subsequent process of cutting the product
