| Abstract | Currently manufacturing a large number of machine parts using CNC turning machine requires efficient planning in choosing components of the turning process. Oblique cutting with tool inserts is a factor affecting such efficiency in using back rake angle appropriately. This research aimed to study factors affecting oblique cutting. The study used back rake angle 30, - 15, 0, 15, and 30 degrees to see how they have an impact on radius force (FR), tangential force (FP) and feed force (FQ). The findings from the study showed that when the higher negative bake rake angle value was given, the more cutting force was required; and the cutting force decreased when the lower negative bake rake angle was used. When the higher positive bake rake angle value was given, the more cutting force was required as well. Similarly, considered contributing factors like feed and depth of cut, the cutting force would increase and decrease depending on the value of bake rake angle significantly, both positive and negative. All cutting forces are equal both positive and negative from the experimental results, ranging from radius force (FR), tangential force (FP), and feed force (FQ), respectively. The study results can be adopted to design back rake angles for greater efficiency. |
