Study on the Cutting Properties about Magnesium Alloy when Dry Turning with Kentanium Cutting Tools

Abstract

In recent years, the machinability of magnesium alloy is concerned more and more by the public. In this paper, a study on the cutting properties of magnesium alloy AZ91D when dry turning with kentanium cutting tools is presented. It shows the cutting force measured by a data acquisition system which is made up of Kistler9257B piezoelectric crystal sensor dynamometer, Kistler5070A10100 charge amplifier and computer. The effect of cutting parameters on cutting force was studied, and the experimental formula was built. The tool wear and chip characteristics were observed with KYKY-EM3200 electron scanning microscope and EDAX PV9900 alpha ray spectrometer, while the surface roughness of the workpiece was measured with 2205 profilometer. Results showed that the cutting depth was the main influence factor on cutting force, followed by feed rate and cutting speed . The main form of tool wear showed to be diffusive wear and adhesive wear. The feed rate had the main influence on chip form and the workpiece surface roughness, cutting speed was less effective, the cutting depth was the least.

“…The main form of tool wear showed to be diffusive wear and adhesive wear. The feed rate f had the main influence on chip form and the workpiece surface roughness, cutting speed v was less effective, the cutting depth was the least [11].…”

Measurement and optimization of surface roughness and tool wear via grey relational analysis, TOPSIS and RSA techniques

“…The crumb formation revealed that cutting feed was most effective on the shape of crumbs. Also it was reported that with the increasing of the speed and feed, fractures would appear on the surface of crumbs, and would be changed into cracked crumbs gradually [14].…”

Analysis of Tool Wear and Chip Morphology during Turning of AZ31B Magnesium Alloy under Dry Environment

“…The reported optimum machining combination to secure minimum surface roughness was 0.04 mm/rev as the feed rate, 280 rpm as the spindle speed, and coating with TP2500. A study on the dry turning of AZ91D magnesium alloy using titanium cutting tools was reported by Guo et al [15]. They found depth of cut and feed rate to be the most influential parameters for cutting forces and surface roughness, respectively.…”
