Abstract

PURPOSE:To improve both the quality and efficiency with a numerical controller by applying correction automatically to the cutting conditions decided by the materials to be cut and the materials of tools, the limitation due to characteristics of each machine and the limitation due to the processing form and method respectively. CONSTITUTION:The program data supplied through a data input part 01 are stored temporarily in an input data memory part 02. Then this data is transferred to an arithmetic part 03 and stored to a program data memory part 05 through a program data processing part 04 as long as this input data is equal to the data on the material to be cut and the tool material. If the input data is equal to the cutting condition data, the part 03 reads the material to be cut and the tool material set by the cutting condition data via the part 04 out of the part 05. Then the part 03 selects the cutting condition memory parts 101, 102- corresponding to the combinations of data on the materials to be cut and the tool material and then selects the corresponding cutting conditions among cutting condition memory parts 11, 12-. Then the corresponding coefficient is selected among coefficient memory parts 200, 300- and calculated with the cutting conditions selected previously. The result of this operation is stored to the part 05 sthrough the part 04.
