no. 1 Embodiment approach

[0026] Below, according to Figure 1 to Figure 7 A wire saw (device) embodying the first embodiment of the present invention will be described.

[0027] Such as figure 1 As shown, a plurality of processing grooved rolls (hereinafter referred to as processing rolls) 11 are rotatably supported by a wire saw device frame (not shown) on parallel axes. Generally, two to four are mounted as the processing rollers 11, and two are mounted in this embodiment. A plurality of annular grooves (not shown) are formed at equal intervals on the outer periphery of the processing roller 11 , and a wire 13 for workpiece cutting is wound helically in the annular grooves. The wire rod 13 is a fixed abrasive wire rod, and the outer periphery of the carbon steel core wire of the wire rod 13 is fixed and held with abrasive grains such as diamond or white corundum using an adhesive.

[0028] And, in this embodiment, one of the two processing rollers 11 passes figure 2 The motor 12 shown alternate...

no. 2 Embodiment approach

[0044] Next, according to Figure 5 with Figure 8 , the second embodiment of the present invention will be described focusing on the parts different from the first embodiment.

[0045] In the second embodiment, in order to judge the thickness of the wire 13, the physical attenuation characteristic of the wire 13 is detected. That is, in Figure 8 In the flow chart of , the property detection and storage of the wire 13 by the dancer arm 19 in S2 before the processing starts will be described. After the vibration of the dancer arm 19 ends, as Figure 5 As shown, the sensor 25 detects the convergence time β of the remaining stretching motion of the wire 13 as the property of the wire 13 in S2. That is, in Figure 8 In S11 shown, the CPU 31 recognizes the detection output of the sensor 25 indicating the convergence time β from the end of excitation to the convergence of the remaining expansion and contraction of the wire 13, and calculates the attenuation characteristic of t...

Abstract

The invention provides a method for setting operating parameters of a wire saw and the wire saw. A wire saw is provided with: a plurality of processing rollers; and a wire rod that travels between theprocessing rollers in a surrounding state. The workpiece is cut by the wire rod by processing the feeding workpiece in a wire rod-based cutting region between the processing rollers. The setting method comprises the steps that before a workpiece is machined, a wire is changed; determining the mechanical characteristics of the wire from the state change of the wire; and setting operating parameters of the wire saw according to the mechanical characteristics.

Description

technical field [0001] The present invention relates to a method for setting operating parameters of a wire saw for cutting and processing workpieces made of brittle materials such as semiconductor materials, magnetic materials, and ceramics through wire rods, and the wire saw. Background technique [0002] There are various types of wires having different diameters and materials as wires used for cutting workpieces in wire saws, and it is possible to select a wire suitable for working conditions. And, corresponding to the selected wire, the operating parameters of the wire saw are set. Through the setting of this parameter, adjust the tension given to the wire, or adjust the feed speed of the workpiece and the walking speed of the wire, so that the wire will not break, and the required processing accuracy and processing speed can be obtained. [0003] However, in the wire saw disclosed in Japanese Patent Application Laid-Open No. 8-174402, in order to determine whether the...
