Sharpening method of wavy edge of different material for cutter

Abstract

The sharpening method of wavy edge of different material for cutter includes the following steps: 1. determining the connecting points comprising planar curve and / or linear section comprising the edge end; 2. calculating the polar angle corresponding to planar curve and / or linear section comprising the edge end; 3. setting perimeter coordination system; 4. determining the planar feeding step length of planar curve and / or linear section comprising the edge end and the coordinates of planar feeding step length points; 5. calculating the z coordinates of the step length points; 6. feeding to new coordinate; and 7. repeating the steps from 3 to 6 one section by one section until completing sharpening all the edge curves. The present invention adopts numerically controlled machine tool with parameter programming function to realize the automatic sharpening and has high sharpening precision and greatly raised efficiency.

Description

technical field [0001] The invention relates to a numerically controlled blade sharpening and sharpening technology, in particular to a method for sharpening and sharpening the wavy edge of a heterosexual cutter. Background technique [0002] Heterosexual cutters refer to cutting knives used in the food industry or other occasions that are designed to contain a variety of geometric elements on a plane to form various artistic shapes. One of its functions is to complete the cutting of the material to be cut, and the other is to make the cut material consistent with the plane shape of the cutter. Under normal circumstances, the shape of this kind of cutting knife is that various geometric curves are connected end to end on the plane to form a closed polyline, and the knife edge is made into a wave shape in the normal direction of the plane, so that the cutting knife is sharp when it penetrates into the material to be cut. . [0003] The CNC cutting edge ...

Problems solved by technology

In the existing numerical control system, there is generally only the direct interpolation function for straight lines and circular arcs (some numerical control systems contain some direct interpolation functions that can express curves such as parabolas with simple equations), and the wavy shape of this special-shaped cutter The cutting edge is a spatial curve that cannot be described by equations in the Cartesian coordinate system, and it cannot be directly programmed with the instructions of the existing CNC language. Therefore, the wavy cutting edge of this special-shaped cutter cannot be sharpened by CNC sharpening technology. and sharpening, while manual sharpening and sharpening are difficult to ensure quality
