Problems solved by technology

However, at present, in the operation of the machining center of the CNC machine tool, there are still frequent occurrences of machine collisions due to insufficient skills of the operator, skipping the program for processing, and correcting the wrong tool compensation.
If the collision is light, it will damage the tool and tooling, and if it is serious, it will cause local damage to the machine tool, reduce the accuracy, and scrap the whole machine, and even endanger the safety of the operator. It will take a long time to resume normal production

Embodiment Construction

[0016] The present invention will be further described below in conjunction with drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0017] Please refer to figure 1 as shown, figure 1 It is a flowchart of a control method for preventing collision of a numerically controlled machine tool provided by an embodiment of the present invention.

[0018] In the present embodiment, the control method for the CNC machine tool to prevent collision specifically includes the following steps:

[0019] Step S101 , judging whether the tool number transferred to the spindle is consistent with the tool number called during actual machining, if they are consistent, execute step S103 , otherwise, exec...

Abstract

The invention discloses a control method and a control system of preventing machine impact for a numerical control machine tool. The method comprises the following steps of A, judging whether the cutting tool number on a spindle is consistent with the cutting tool number which is used in practical processing, if so, executing the step C, and if not, executing the step D; B, judging whether the change amount of the cutting tool length before and after cutting tool compensation is smaller than a preset threshold value, if so, executing the step C, and if not, executing the step D; C, normally executing the processing procedures; D, alarming. According to the control method of preventing machine impact for the numerical control machine tool, which is provided by the invention, the machine impact problem which is caused by procedure skip processing of an operator and the wrong input cutting tool compensation is solved, and the occurrence of the machine impact is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tool control, in particular to a control method and system for preventing collision of a numerical control machine tool.
