Intelligent lathe control method

Abstract

The invention discloses an intelligent lathe control method. The method comprises the following steps: 1, in a processing process, current of a main motor and a deviation value returned by a grating ruler are detected in real time, a change deltaaf for a feed rate af serves as a system adjustment amount, and closed-loop feedback learning control during the processing process is realized; and 2, during a workpiece processing process, the vibration condition of a lathe workpiece serves as an input value, a particle swarm optimization algorithm is adopted to set servo driver parameters, and the system can operate more stably. Self setting of parameters of a numerical control driving device can be realized, the numerical control system can timely acquire workpiece configuration error information, and adjustment on parameters of a subsequent process are facilitated.

Description

technical field [0001] The invention relates to a lathe control method, in particular to an intelligent lathe control method. Background technique [0002] The CNC system is the core control unit of the CNC machine tool, which can fully control the movement and processing process of the machine tool. And has the following functions: number of control axes and linkage axes; interpolation function; feed function; spindle function; tool function; tool compensation; mechanical error compensation; operation function; program management function; character graphic display function; auxiliary programming function; Automatic diagnosis and alarm function; communication function. For a NC machining program, if there is a logic error, the system's automatic diagnosis and alarm function will prompt modification, but for the unreasonable selection of processing parameters in the program, the automatic diagnosis and alarm function can do nothing. Therefore, the execution of such a progr...

Problems solved by technology

These equipments play a key and even core role in processing quality and efficiency, and are often quite expensive to manufacture; even some processed products, due to their complexity, precision or large-scale features, have a unit cost or processing cost that is quite astonishing.

In this case, damage to processing equipment or product scrapping or even just a reduction in processing efficiency can cause huge losses

[0004] Traditionally, the setting of processing parameters is based on human experience or related manuals, but it is difficult to give better processing parameters for beginners or even skilled operators, and because the setting of processing parameters involves Human operation, there may be hand errors, etc., which may give wrong or even endanger the processing parameters of machine tools, tools and workpieces, and these cannot be detected by the system's decoding error detection
