Skin mirror image milling numerical control program fast generating method based on features

Abstract

A skin mirror image milling numerical control program fast generating method based on features includes: performing machining area division according to machine tool travel and the actual size of a skin piece, and identifying skin piece area features; determining the frame bent distribution information of each machining area and information such as feature machining sequence and cutting parameters of the current area, and building a skin middle layer process curved surface for automatic tool trajectory calculation; performing automatic numeral control programming based on the features on a machine tool spindle and top support according to tool trajectory information, adjusting frame bent positions through interference judgment, and outputting a final numerical control program for driving the machine tool to perform fast machining. The method has the advantages that by the skin mirror image milling fast numerical control programming based on the features, the tool trajectory compiling cycle is shortened, automatic numerical control programming of the machining spindle and automatic numerical control programming of the top support are achieved, programming's dependence on human experience is reduced, programming standardization is guaranteed, programming quality is increased, and programming efficiency is increased at the same time.

AI Technical Summary

Benefits of technology

This patented describes an improved way of create computerized tools that can help with processes such as surface treatment or lithography. It achieves this by generating specific patterns from scratches made during machine operation instead of manually selecting them outdoors. These patterned areas then used to make different types of materials like plastics or metal without having to go back into their original form again. Overall, these improvements enhance productivity and reduce costs associated therewith.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the accuracy and speed of automating computer numerical control ("CNC") programs used in skin mirrormilling processes that require accurate data analysis due to factors like uneven or partially covered areas caused by human body movements. Current methods involve manual editing of the processed region map beforehand, adding layers between different locations without considering these issues. Additionally, current tools have limitations in terms of their ability to handle nonlinear shapes, making it difficult to achieve precise depth measurements while maintaining stable operation.
