Influence of pilot hole on cutting force during threading with wireless holder system

Autor: Shota MATSUI, Nobutoshi OZAKI, Toshiki HIROGAKI, Eiichi AOYAMA, Ryo MATSUDA

Publikováno v: Journal of Advanced Mechanical Design, Systems, and Manufacturing, Vol 18, Iss 4, Pp JAMDSM0040-JAMDSM0040 (2024)

This paper examines the machining accuracy when simultaneously machining pilot holes and threads, and the machining accuracy when machining threads after pilot hole drilling. To verify them, cutting forces were measured in the tool rotation coordinat

Verification of pattern formation mechanism using voxel model and estimation accuracy for inverse analysis of vibration phenomenon using two-dimensional discrete Fourier transform of end mill chatter mark

Autor: Nobutoshi OZAKI, Haruki MINETAKA, Shota MATSUI, Toshiki HIROGAKI, Eiichi AOYAMA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 87, Iss 899, Pp 21-00095-21-00095 (2021)

The vibration generated at the contact point between a tool blade and a machined surface during cutting significantly influences the generation mechanism of regenerated chatter vibration. However, it is difficult to measure the vibrations generated a

State estimation based on image processing of chatter mark on end-milled surface by two-dimensional discrete Fourier transform

Autor: Nobutoshi OZAKI, Shota MATSUI, Toshiki HIROGAKI, Eiichi AOYAMA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 85, Iss 879, Pp 19-00292-19-00292 (2019)

In this report, we propose a method to analyze the frequency and phase difference of self-excited vibration during cutting by using image analysis for the photographed image of the machined surface by end milling. It is widely known that, when chatte

Investigation of Internal Thread Cutting Phenomena in Three Axes by Controlling Helical Interpolate Motion Considering Tool Position Information from Servo-Drive

Autor: Shota Matsui, Takamasa Yamamoto, Nobutoshi Ozaki, Eiichi Aoyama, Toshiki Hirogaki

Publikováno v: International Journal of Automation Technology. 14:467-474

In this study, the authors investigate improving the precision of a thread by deriving its radial force (thrust force) with a four-component piezoelectric dynamometer and thread cutting by helical interpolation motion using a thread mill. The accurac
