Double-arc high-feed annular milling cutter and its preparation process and detection method

Abstract

The present invention relates to a preparation process and a monitor method of a double-arc large feed ring mill cutter. Currently, ring mill cutter having curved surface high adaptability is widely used in aerospace, automotive and other mold curved surface semi-finishing field, but in order to achieve better cutting performance, improvement of milling efficiency by breakthroughs in the aspects of cutting feed, cutting forces and the like has certain difficulty, on the other hand, grinding process affects processing efficiency, tool life and surface integrity of a workpiece, meanwhile the method for effectively verifying the accuracy of the grinding is worth of considering. The double-arc large feed ring mill cutter comprises a ring mill cutter handle (1), the front end of the ring mill cutter handle is successively connected with a spiral cutter groove (2), a double-arc large feed cutting edge (3), and an end tooth chip pocket (4), the double-arc large feed cutting edge comprises a main-arc cutting edge (7) and a sub-arc cutting edge (8). The double-arc large feed ring mill cutter is used for milling die steel, at the same time, a reference opinion for the preparation process and the monitor method of the mill cutter is provided.

Description

technical field [0001] The invention relates to a double-arc high-feed annular milling cutter, and specifically relates to a preparation process and a detection method of the annular milling cutter. Background technique [0002] At present, the ring milling cutter has high adaptability to connect the bottom edge and the peripheral edge to participate in the cutting and processing of curved surfaces through the rounded cutting edge, and the step distance of the ring milling cutter relative to the ball end milling cutter is larger in the case of equal residual height processing , reduced processing time, improved processing efficiency and other advantages, it is widely used in the semi-finishing fields of mold surfaces such as aviation, aerospace, and automobiles. In order to achieve better cutting performance, many studies have focused on the optimization of milling parameters and processes, but these studies are bound to be limited by tool structure, machine tool torque and ...

AI Technical Summary

Problems solved by technology

In order to achieve better cutting performance, many studies have focused on the optimization of milling parameters and processes, but these studies are bound to be limited by tool structure, machine tool torque and precision, and it is difficult to further improve processing speed and efficiency.

When using a ring milling cutter to process a mold with a concave surface, it is easy to have a residual step surface; due to the participation of the rounded cutting edge in the cutting process to a certain extent, the feed rate is limited and the cutting force is large
