Problems solved by technology

However, machine tools are generally expensive and it is economically difficult to prepare machine tools for thermal displacement correction training
In addition, training by temporarily suspending workpiece processing using the machine tool actually used for workpiece processing may also affect other processes
[0007] Therefore, in reality, it is difficult for the operator to obtain the opportunity to use the actual machine tool for thermal displacement correction training

Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0019] figure 1 It is a functional block diagram of the thermal displacement correction training device of the present invention. A thermal displacement correction training device 19 related to thermal displacement correction which does not require an actual machine tool is prepared. The operator of the machine tool uses the thermal displacement correction training device 19 to learn the method of thermal displacement correction and the adjustment method of thermal displacement.

[0020] The thermal displacement correction training device 19 includes a virtual machine tool control device 10 , a virtual machine tool device 13 , and a virtual machine tool display device 14 on a computer 18 .

[0021] For the training of machine tool operators, the virtual machine tool device 13 of the thermal displacement correction training device 19 calculates a virtual model of the m...

Abstract

A thermal displacement correction training unit for a machine tool has a virtual machine tool, a virtual machine tool control unit and a virtual machine tool display unit. The virtual machine tool has a precision decline imitating unit for imitating the process precision decline caused by the heat during operation in the virtual machine tool unit, and a precision decline calculation unit for finding the amount of precision decline that represents the process precision decline in the process machine unit imitated by the process precision imitating unit. The virtual machine tool control unit has a precision correction unit for finding the correction amount by which the processing point is corrected in response to thermal displacement, and a correction amount adjustment unit for adjusting the correction amount found by the precision correction unit. The virtual machine tool display unit displays the amount of precision decline calculated by the precision decline calculation unit of the virtual machine tool and the correction amount adjusted by the correction amount adjustment unit.

Description

technical field [0001] The invention relates to a thermal displacement correction training device for simulating the accuracy correction method of a machine tool and its adjustment method on a computer. Background technique [0002] When using a machine tool to process a workpiece, slight displacement occurs in the structure of the machine tool due to the heat generated from the motor, ball screw, and workpiece processing part constituting the machine tool, the cooling of cooling oil or cooling air, and the interference of the outside air temperature ( Hereinafter referred to as "thermal displacement"). As a result, deviation occurs in the machining position of the workpiece, which is one of the factors that greatly affects the machining accuracy. As a countermeasure against this thermal displacement, there is a method of predicting the amount of heat generated during processing and the amount of change in the structure, and correcting the deviation of the processing positi...
