3c die manufacturing precision strict, if using conventional equipment and processing methods (see Figure 3), parts of precision control in a reasonable range, but after completion of error accumulation, will have a corresponding die working parts of dislocation and migration, and directly affects the size and appearance of the product quality. According to the traditional manufacturing process, workers using grinding and blending of remedies and learn from each other, patchwork, although reworked barely reached Mold inspection requirements, but for normal use in the future to stay hidden.
Die cutting process, as a result of cutting force and tool wear mold deformation and manufacture error, created great difficulties for subsequent Assembly. Some irregular surface, tool and workpiece the cutting point change as the processing part of the surface slope, forming uneven cutting step. Angle bead and feed restriction, CNC cut will leave a slight mark on the surface of the mold (see Figure 4). In the context of both production efficiency, workers used grinding and polishing methods, using power tools to remove machine marks, reached the surface roughness requirements under, but excessive polishes may damage the mold surfaces and linear structure, CNC machining, all achievements.
3C products booming in recent years, posed a severe challenge to China's mold enterprises, mold production is inefficient and unstable quality shortcomings are gradually exposed. To resolve technical issues in these areas, only the more advanced intelligence technology, reduce random errors and manual intervention in the process, to avoid the resulting rework, one step to complete the processing of all parts of the content, and radically improve the quality and efficiency of production.
