Process for machining reticulate pattern knurls through macro program

Abstract

The invention discloses a process for machining reticulate pattern knurls through a macro program. The process comprises the following steps of: performing accurate drawing by using two-dimensional CAD software according to a workpiece coordinate system and data on a drawing during processing, so as to convert a machining contour into a functional equation. According to the process for machining reticulate pattern knurls through the macro program, during machining, the workpiece coordinate system serves as a benchmark, the data in the drawing serve as a basis, and the machining contour is converted into a functional equation; and circular indexing is performed, and multi-head forward and reverse alternate thread screwing is performed. According to the process of the invention,advanced CAD and CAM technologies are combined, the numerical control macro program, the calculus thought and the functional trajectory equation are creatively introduced. The process has the advantages of easiness in equipment use, convenient programming and high applicability, and and can be widely applied to machining of reticulate knurled parts.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a technique for processing anilox knurling by using a macro program. Background technique [0002] Anilized knurling is widely used in the mechanical process of rolling patterns on the handles of metal products or other working surfaces, mainly for anti-skid use. Knurling is mostly extruded with a knurling knife, but the quality of the extruded texture is not good, and the processing efficiency is also low, and some thin-walled parts cannot be extruded. [0003] The traditional processing method is the profiling processing method, which has high cutting resistance. When the length and diameter are relatively large, the rigidity of the workpiece will be insufficient, and the process system is prone to serious vibration, which restricts product quality and production efficiency. [0004] In recent years, domestic and foreign knurling manufacturers mostly adopt ...

Problems solved by technology

Knurling is mostly extruded with a knurling knife, but the quality of the extruded texture is not good, and the processing efficiency is also low, and some thin-walled parts cannot be extruded.

[0003] The traditional processing method is the profiling processing method, which has high cutting resistance. When the length and diameter are relatively large, the rigidity of the workpiece will be insufficient, and the process system is prone to serious vibration, which restricts product quality and production efficiency.

[0004] In recent years, domestic and foreign knurling manufacturers mostly adopt the method of double-wheel extrusion knurling to process knurling, which greatly improves the quality and production efficiency of knurling. Large spindle damage, poor applicability

[0005] With the rapid development of CAD and CAM technology, some manufacturers have begun to use the thread cutting command G32 for anilox knurling processing. This method has advanced ideas and can be completed by ordinary CNC machines, but the programming is complicated and the applicability of the program is poor. Often "one hair moves the whole body"
