Problems solved by technology
[0003] When the existing wire cutting machine is in use, the parts to be processed are placed on the processing table. Due to the irregularities of the parts or the burrs around the parts, the parts to be processed will not be in a horizontal state, that is, the electrode wire cannot be accurately aligned. , and before processing, it is necessary to move the processing table to determine the accurate calibration between the parts to be processed and the electrode wire, but at present, most of them use manual adjustment, which seriously affects the efficiency of processing, and the alignment is also subjective. It leads to inaccurate alignment and affects the machining accuracy of the parts to be processed

Embodiment Construction
[0024] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:
[0025] Such as figure 1 Shown, a kind of method for automatic calibration of wire cutting machine tool, it comprises the following steps:
[0026] The first step is to first determine the reference point A of the electrode wire of the wire cutting machine, and determine the reference line with this reference point A. When the electrode wire touches the edge of the strip cutting part, it is used as the reference point A, and then the Make a horizontal line as a baseline;
[0027] The second step is to take the reference point A as the starting point, and divide and determine each point B along the edge of the part to be processed. n , and determine each point B n The distance L to the base line n , with the reference point A as the starting point, move to the outside for a certain distance L, and move downward for a certain distance S, and then move to th...

The invention provides an automatic correction method for a linear cutting machine and a linear cutting machine. The method comprises the steps that 1, a reference point A of a wire electrode of the linear cutting machine is determined at first, and a reference line is determined on the basis of the reference point A; 2, the reference point A is adopted as an initial point, halving is performed on a part to be machined to determine all points Bn, and the distance Ln between the reference line and each point Bn is determined; 3, according to the distance Ln obtained in the second step, a deflection angle alpha of the part to be machined is obtained; 4, the linear cutting machine can automatically perform replanning on a cut line according to the obtained deflection angle alpha. According to the method, the distance between the edge of the part to be machined and the reference line is directly detected, the deflection angle of the part to be machined is obtained, then, the cutting line is automatically corrected according to the deflection angle, complexity of independent alignment of an operator needed in the prior art is omitted, and the linear cutting machining efficiency is greatly improved.
Description
technical field [0001] The invention relates to the field of wire-cut machine tools, in particular to an automatic calibration method for wire-cut machine tools and the wire-cut machine tool. Background technique [0002] In WEDM, firstly, it is necessary to properly clamp the workpiece and accurately locate the electrode wire, which is an important process step, which determines the success or failure of the part processing. [0003] When the existing wire cutting machine is in use, the parts to be processed are placed on the processing table. Due to the irregularities of the parts or the burrs around the parts, the parts to be processed will not be in a horizontal state, that is, the electrode wire cannot be accurately aligned. , and before processing, it is necessary to move the processing table to determine the accurate calibration between the parts to be processed and the electrode wire, but at present, most of them use manual adjustment, which seriously affects the eff...
