Embodiment Construction
[0069] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0070] Step 1: Define the geometric parameters related to the forming edge of the woodworking milling cutter
[0071] (1) Eccentric value H: Define the distance between the plane where the forming edge is located and the center plane of tool rotation as H.
[0072] (2) Point P on the cross-sectional shape of the rotary contour axis of the cutting edge: Woodworking forming milling cutters usually have a known rotary shape of the blade, and point P is defined as the point on the cross-sectional shape of the rotary contour axis of the forming edge.
[0073] (3) Grinding point P 0 : Define the grinding point on the cutting edge under the workpiece coordinate system as P 0 point.
[0074] (4) Grinding point P on the flank end 0 Corresponding point P 1 : over grinding point P 0 Make a plane perpendicular to the flank, and its intersec...

The invention discloses a method for solving the grinding trajectory of the flank of a woodworking milling cutter. Firstly, the relevant geometric parameters of the woodworking forming edge are defined, the workpiece coordinate system and the cutting edge coordinate system are defined, and the forming edge and the flank of the woodworking milling cutter are defined. , considering the impact of the grinding wheel swing angle and lift angle on the initial attitude, calculate the grinding wheel trajectory, and finally determine the description of the grinding wheel trajectory in the workpiece coordinate system. The invention uses a flexible grinding attitude of the grinding wheel to cope with the flexible and changeable irregular edge line of the forming blade, and can realize the flexibility of the definition of the grinding attitude of the grinding wheel by judging the position of the grinding point while ensuring the grinding quality Sex, so as to ensure the accuracy of the relief angle and avoid interference.
Description
technical field [0001] The invention belongs to the technical field of woodworking forming milling cutter manufacturing, and in particular relates to a method for solving the grinding trajectory of the flank face of a woodworking forming milling cutter. Background technique [0002] With the development of the woodworking tool market, higher requirements are put forward for the research and development and development direction of woodworking tools. The molding method of woodworking milling cutters is similar to that of metal milling cutters, but compared with metal milling cutters, woodworking milling cutters have the characteristics of larger rake angles, larger rear angles, fewer cutting teeth, and larger length and shape spans of cutting edges. The existing research on the grinding trajectory of metal milling cutters cannot be directly applied to woodworking milling cutters. Therefore, it is of great significance to study the flank grinding method of woodworking form mi...
