Method and device for influencing the cutting and functional areas on fine-cut finished parts

摘要

The method involves cutting a blank with a defined material allowance relative to a contour of the finished section in an area of the reduction. The size of the blank within the first working stage is adjusted to a stipulated degree to a material volumes that fills up, compensates or exceeds the volume deficit that occurs due to the reduction to a preset value. The material volume is subsequently shifted in a forming process opposite the cutting direction of the first working stage on the cutting line of the blank to purposefully fill up the developed reduction during a second working stage. An independent claim is included for a device for influencing cut and functional face on fine-blanked finished sections for gear or cut out of metal strip.
