Automatic generation device for machine control command and parameter and its method

Abstract

The invention provides a command and parameter generating device comprising an interpreting module, a planning module, a simulation analysis module and an optimization calculus module. The command and parameter generating method includes that the interpreting module interprets the workpiece program to produce the track coordinates of the workpiece; the planning module interpolates the trajectory coordinates and generates the path information and velocity information of the tool; the simulation analysis module analyzes the trajectory characteristics of the tool by the path information and velocity information, and gives the cutting simulation message; and the optimization calculation module generates the optimal control parameters of the corresponding block according to the trajectory characteristics of the different blocks of the workpiece and the cutting simulation quality. The device described in the present invention is an auxiliary device which can be arranged independently of the machine control system or as a subunit of the machine control system and operates in the machine control system.

Description

technical field [0001] The invention relates to an automatic generation device and automatic generation method of control instructions and parameters in a machine tool, in particular, it refers to the optimization control of the workpiece through the prior simulation analysis and calculation, aiming at the different motion track characteristics and simulated cutting quality of each block. A parameter generating device and a generating method. Background technique [0002] see Figure 1A The known numerical control method of a machine tool shown is mainly to adjust and determine the processing parameters for the trajectory planning and motion control of the tool during the actual processing. Therefore, in the face of diverse processing When the workpiece contains various tool paths with different characteristics, the processing quality and efficiency can only be limited to a set of fixed parameters. [0003] see Figure 1B In another known numerical control method for machi...

Problems solved by technology

[0005] However, even if the aforementioned three known numerical control methods for machine tools can partially solve the limitations between fixed parameters and actual processing quality and efficiency, they still cannot avoid the waste of time and resources caused by repeated actual testing and processing modifications.
