Set-Up of a Test Bench for the Investigation of Single Parameter Effects in Abrasive Processes by Force Measurements

Abstract

Abrasive processes are influenced by many different parameters. For a systematic investigation of these influencing parameters, a test bench for abrasive tools has been developed and set up on a 3-axis milling machine. The test bench is capable to control the machining parameters, such as the cutting speed and the feed speed, regulate the lubrication conditions, such as the temperature or the flow rate, and measure the cutting force during the process. Impacts of the single force components are investigated by means of the abrasive tools in contact with the rotating workpieces and the calculation of the tangential force coefficient. In this paper, the set-up of the test bench is explained and the systematic proceeding in investigating the impacts is exemplified by cooling lubricants because the surface of the workpiece, the wear of the tool, the temperature and the friction forces are often influenced by the type of cooling lubricant and its composition. The aim of the test bench for tools is to understand the correlations of the single influencing parameters in abrasive processes. The first results of comparative investigations with cooling lubricants of different viscosities are presented and discussed.

Wear Characterization of Cemented Carbides (WC–CoNi) Processed by Laser Surface Texturing under Abrasive Machining Conditions

“…The abrasive machining test of the laser-shaped hexagonal pyramids have been carried out by means of an in-house test bench, which is constructed on the basis of external honing processes (Figure 2a) [18]. This workbench can characterize the abrasive machining processes by force measurement (Figure 2b).…”
