Title:
HOLE PROCESSING TOOL, AND DESIGN METHOD, MANUFACTURING METHOD, AND EVALUATION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2020/090594
Kind Code:
A1
Abstract:
Provided is a method for simply evaluating a simulation result on the basis of the Matsuzaki-Liu model. This hole processing tool for forming a hole is provided with a plurality of cutting edges, wherein when the cutting edges are applied to the Matsuzaki-Liu characteristic equation, the maximum real part TσMAX is in the range of a predetermined threshold with respect to the maximum real part RσMAXX of a reference hole processing tool if No is the integer value closest to the imaginary part of a quasi-static characteristic root s, which is a characteristic root at the vibration frequency ω=0, and if the maximum real part σMAX is the maximum real part of the quasi-static characteristic root s that satisfies 3≤No≤2n+1 (n is the number of cutting edges).
