Problems solved by technology

[0002] CNC lathes are widely used to process rotary parts. From the structural point of view, many parts have the rotary characteristics of lathe parts and typical milling characteristics. For the processing of this type of parts, traditionally, it is necessary to target different types of features. Processing on CNC lathes or CNC milling machines requires turnover on different machine tools, repeated clamping and positioning, which will cause clamping and positioning errors and make the production preparation cycle too long

Abstract

The invention relates to the field of numerical control processing in the aspect of machine manufacturing, and discloses an intelligent and automatic compilation method for a non-cylindrical curved surface numerical control turning processing program. The method aims at a wireframe model, a curved surface model and an entity model part, and information such as processed non-cylindrical curved surface is acquired by performing feature identification on the models. A processing coordinate system is set, a cutting cutter is defined, and a cutting parameter is set. Processing adaptability detection is conducted, non-cylindrical curved surface numerical control turning intelligent programming operation is defined, interpolate points are calculated, and a processing program is generated through post-processing. By the numerical control turning processing automatic and intelligent programming method, the processing range of a numerical control lathe is enlarged, and programming quality and efficiency are improved, so that part processing quality and efficiency are improved.

Description

technical field [0001] The invention relates to an automatic intelligent programming method for numerical control turning, in particular to an intelligent and automatic programming method for numerical control turning of non-cylindrical curved surfaces. The method belongs to the subject field of numerical control processing technology and programming in mechanical manufacturing. Background technique [0002] CNC lathes are widely used to process rotary parts. From the structural point of view, many parts have the rotary characteristics of lathe parts and typical milling characteristics. For the processing of this type of parts, traditionally, it is necessary to target different types of features. Processing on CNC lathes or CNC milling machines requires turnover on different machine tools, repeated clamping and positioning, which will cause clamping and positioning errors and make the production preparation cycle too long. [0003] From the perspective of processing efficie...
