Numerical control machine tool magazine tool information storage and calling method

Abstract

The invention discloses a numerical control machine tool magazine tool information storage and calling method. The method comprises the following steps that S1, a unified tool number T is set for each type of tools, the same tool number has the same tool handle model, theoretical tool length, theoretical radius, tooth number, base angle and other tool parameters, and the tool number has uniqueness; S2, a tool position number m is set from the number 1 for each tool position in a tool magazine, the each tool with the corresponding tool number in the S1 is mounted on the corresponding toolposition with the corresponding tool position number in the tool magazine, and the tool position number of the machine tool main shaft end is set to be 0; S3, a certain number of variable registers are distributed for each tool position number in a machine tool numerical control system, the variable registers are used for storing the tool position numbers, the tool numbers and the tool parameterscorresponding to the tool numbers, and a tool information register data storage table is established; and S4, programming is carried out by using the tool numbers, and operating and calling of the tools are started by the numerical control machine tool according to a set program. According to the method, a machine tool can have the functions of storing and calling more than or equal to 10000 types of tool numbers and tools.

Description

technical field [0001] The invention specifically relates to a method for storing and calling tool information of a CNC machine tool, which is used for storing and calling tool position numbers and tool information of a tool magazine of the CNC machine tool, and belongs to the field of automatic processing of the CNC machine tool. Background technique [0002] At present, in the tool magazine widely used in CNC machine tools, there is a one-to-one fixed correspondence between the tool number and the tool position number. This method makes the number of tool numbers limited by the number of tool positions, which is not conducive to the expansion of tool types. [0003] The products processed by the same tool type in different periods are different, and the tools used in the program are also different. Especially when there are many types of tools involved in product processing, the same tool number will correspond to different types of tools at different times. It is necessary...
