Title:
工作機械の熱変位の補正方法
Document Type and Number:
Japanese Patent JP6910057
Kind Code:
B2
Abstract:
To provide a correction method of thermal displacement which can select and change a correction coefficient (an environmental parameter) based on a change amount of an environmental temperature in correcting thermal displacement of a machine tool.SOLUTION: A recording part records a temporal change of an environmental temperature. A correction coefficient of thermal displacement caused by a change of the environmental temperature is set at a start of next operation based on an environmental temperature change amount at a previous operation.SELECTED DRAWING: Figure 1
