Tool wear measurement in single point incremental forming

Abstract

Forming tool in manufacturing industries plays a vital role in processing and finished part surface profile. Tool wear in single point incremental forming (SPIF) is studied in the present study with the aim to investigate the effect of input parameters. Image tool wizard of MATLAB R2010a software is used for the wear measurement. The image of tool end is transformed into the histogram plot and the difference of bar length is measured as wear. For experiment, six parameters, namely step depth, feed rate, spindle speed, thickness of material, wall angle and lubricant are considered for SPIF of aluminum AA3003-O. Experiments are being made based on the Taguchi technique followed by ANOVA analysis to study the effect of process parameters and the image analysis is used for the measurement of tool wear. The results shows that the significant input parameters are step depth, feed rate of tool and spindle speed for tool wear whereas wall angle is insignificant.
