Abstract

This invention relates to mechanic design process field and relates to one complex shape equal height cut combination digital control process method, which comprises complex shape cut design, module establishing, digital cutting, and shape combination. This invention can fulfill usual digital control bed process complexity task and eliminate the cut process knife problem without any change of knife tool and machine bed functions.

Description

technical field [0001] The invention relates to the field of mechanical design, manufacture and processing, in particular to a manufacturing method of contour division combined numerical control milling of complex shapes. Background technique [0002] Before CNC milling technology was applied to mechanical manufacturing, the cutting of mechanical parts and prototypes (abbreviation: complex shapes) with complex surfaces could only be performed by manually controlled machinery, or even engraved by hand tools. Therefore, it could not achieve high precision. precision and efficiency. After the CNC milling technology is used in the processing of complex shapes, the processing accuracy and efficiency are significantly improved, and it has become the main method for the manufacture of precise and complex shapes of metal materials. However, due to the limitations of the tool structure and machine tool functions, some deep cavities still cannot be cut, and it is difficult to meet th...
