Abstract
Mechanical micro machining is an ideal method to produce high accuracy micro components and micro-milling is the most flexible enabling process and is thus able to generate a wider variety of complex micro components. Machine table is one of the key element of micro-milling machine. Most of Micro milling table consist of slides/guides, recirculating ball screw and air bearing. In most the linear motion guides are used for accurate linear movements. While studying the literature available on micro-milling, there is little information available on mechanical structure like linear motion guide required for the machine to meet desired accuracy and therefore detail study of the table of micro-milling is required. This work attempts to complete study of table for micro-milling within frame work of FEA, in order to assure the desired performance of micromilling machine. However, no systematic design and analysis procedure is available / reported before in the available literature. Finite Element Analysis of Micromilling table is carried out on Static Stress Analysis (Von Mises Analysis), Dynamic Analysis and Modal Analysis aspects of analysis to evaluate the response of micromilling table. In this attempt the response of micromilling table has obtained in the form of frequency, amplitude, compliance and stiffness.
