Development of meso-scale milling machine tool and its performance analysis

Abstract

To overcome the shortcomings of current technologies for meso-scale manufacturing such as MEMS and ultra precision machining, this paper focuses on the investigations on the meso milling process with a miniaturized machine tool. First, the related technologies for the process mechanism studies are investigated based on the analysis of the characteristics of the meso milling process. An overview of the key issues is presented and research approaches are also proposed. Then, a mesoscale milling machine tool system is developed. The subsystems and their specifications are described in detail. Finally, some tests are conducted to evaluate the performance of the system. These tests consist of precision measurement of the positioning subsystem, the test for machining precision evaluation, and the experiments for machining mechanical parts with complex features. Through test analysis, the meso milling process with a miniaturized machine tool is proved to be feasible and applicable for meso manufacturing.

Limits, Modeling and Design of High-Speed Permanent Magnet Machines

“…Many academic institutions, mainly in Europe and Asia, have been directing efforts toward the development and commercialization of smaller, even desktop-sized micro-cutting machines. These efforts have resulted in a number of compact, three to five-axis, mainly micromilling machines [7][8][9][10][11][12][13][14][15][16][17].…”

“…[123]), whose findings are confirmed with experimental results [124], define a reference stress as a criterion for elastic failure. For the plane stress condition Tresca's reference stress is defined as [80]: 13) and von Mises' reference stress as:…”

Development of an Integrated Approach to the Design of Reconfigurable Micro/Mesoscale CNC Machine Tools

“…Most of these components fall into the scales from ten microns to one millimeter, which is known as mesoscale in mechanical engineering. Current trends toward product miniaturization require fabrication techniques that can efficiently and economically produce mesoscale components with complex microfeatures over a wide range of material types [2].…”

Single Grit Grinding Simulation by Using Finite Element Analysis

“…Most researches revealed that the size effect, cutter edge radius and minimum undeformed chip thickness in micro machining (milling, turning etc.) has similar effects on micro grinding process [7]. Ohbuchi and Obikawa [8] investigated the surface generation of grinding considering the grit shape and cutting speed.…”
