Automatic machining method of numerical control machine tool

Abstract

The invention discloses an automatic machining method of a numerical control machine tool, and relates to the technical field of automatic machining of the numerical control machine tool. According to a three-dimensional model and characteristic parameters of a to-be-machined workpiece of the numerical control machine tool, in combination with priori machined workpiece data stored in a database, and in combination with generated machining paths and process parameters, an execution path and an execution clamp are screened; the method has the advantages that workload is low, objectivity is high, automatic machining efficiency of the numerical control machine tool is improved, waste products caused by damage to workpieces to be machined are avoided, and first feeding speed parameters of the numerical control machine tool are preliminarily determined on the basis of mechanical property characteristic parameters of the numerical control machine tool in combination with required roughness, required precision and cutters of the workpieces to be machined of the numerical control machine tool; and then the feeding speed parameter of the execution path of the to-be-machined workpiece of the numerical control machine tool is determined through the feeding depth of the execution path of the to-be-machined workpiece, and the normalization is high, so that the suitability of a produced product with required precision and required roughness is guaranteed.
