Design of Robust Grinding Wheel Reciprocating Arrangement for Precision Point-grinding Machining

This research is to investigate the dynamic characteristics of the grinding process. A kind of robust grinding wheel reciprocating arrangement is schemed out, which realizes the precise point-grinding machining. The grinding wheel reciprocating movement is driven by a linear motor to replace the traditional crank or hydraulic pressure drive device. Based on the time series method, the modal exp...

Understanding of Ultrasonic Assisted Machining with Diamond Grinding Tool

In this work, machining test was carried out in various machining conditions using ultrasonic vibration capable CNC machine. For work material, alumina ceramic (Al2O3) was used while for tool material diamond electroplated grinding wheel was used. To evaluate ultrasonic vibration effect, grinding test was performed with and without ultrasonic vibration in same machining condition. In ultrasonic...

Simulation and verification of belt grinding with industrial robots

A new simulation and verification system of belt grinding with industrial robots is presented in this paper. The workpiece surface is represented by a discrete height field, an array of extended height segments, and a fast collision detection algorithm using k-DOP bounding volumes is adopted to accelerate the localization of the contact area. A local grinding model is incorporated to decide the...

Efficiency of Dust Capture from Metal Grinding

According to the Machinery Directive 2006/42/EC, one of the essential requirements relating to occupational safety and health hazards is to prevent dust pollution emitted by machinery during the implementation processes. Research on evaluation of emissions from machinery, according to the method of test bench using tracer gases, are currently being conducted in CIOP-PIB. This article presents s...
