Embodiment approach 1

[0032] figure 1 It is a diagram showing the hardware configuration of the electrical discharge machining device according to Embodiment 1 of the present invention. The electrical discharge machining device 100 includes: a spindle 15 ; a spindle drive unit 14 holding the spindle 15 ; a base 11 ; and a table 13 fixed to the base 11 . The spindle drive unit 14 has a drive mechanism that is driven under the positioning control of the control device 10 . Specifically, the spindle drive unit 14 moves the electrodes fixed on the spindle 15 up and down (z-axis direction), left and right (x-axis direction) relative to the table 13 based on the position command value (hereinafter simply referred to as command value) output by the control device 10 . direction) and back and forth (y-axis direction) movement. A processing tank wall 12 is provided on the base 11, and a processing tank is formed by the upper surface of the base 11 and the processing tank wall 12, and the processing tank i...

Abstract

In order to perform correction as effective as possible in response to the ambient temperature of the installation site, the electrical discharge machining device (100) has a temperature-displacement measuring unit (31) that measures changes in the displacement of the reference position and temperature sensors (18a to 18c ) detection value change; the correction coefficient calculation part (32), which calculates the correction coefficient calculation value (43) based on the measurement results of the temperature and displacement measurement part (31); the confirmation display part (33), which displays the temperature and displacement measurement The measurement result of the part (31), and prompts for input indicating whether to use the calculated value of the correction coefficient (43); and the change approval confirmation part (35), when receiving the input indicating the use of the calculated value of the correction coefficient (43), The correction coefficient setting value (41) stored in the correction coefficient setting value storage unit (34) is updated with the correction coefficient calculation value (43).

Description

technical field [0001] The present invention relates to an electrical discharge machining device and an electrical discharge machining system capable of positioning control of a machining position. Background technique [0002] At present, the following structure is installed in the electrical discharge machining device, that is, in order to reduce the influence of the thermal displacement of the spindle caused by the temperature change of the surrounding environment on the machining, the temperature is measured by several temperature sensors, and the measured value is multiplied by Positioning correction is performed by calculating the correction amount with a fixed coefficient. Coefficients (correction coefficients) used for this correction are generally based on experiments by the manufacturer, and are set to fixed values ​​at the time of shipment. [0003] However, the temperature environment in which the electric discharge machining device is actually installed is diff...
