This document summarizes an experimental study on the effect of cutting parameters on cutting force during the turning process. Experiments were conducted on a lathe to study the influence of cutting speed, feed rate, and depth of cut on cutting force and surface roughness. Analysis of variance (ANOVA) found that depth of cut and the interaction between feed and depth of cut significantly affected cutting force. Feed rate, and the interaction between speed and feed most influenced surface roughness. Regression models were developed for cutting force and surface roughness based on the experimental results.
