Abstract

this paper deals with better understanding of the machining conditions that result in improved machinability of elastomers. A series of cutting experiments under different Rake angle, Spindle speed, Feed and constant Depth of cut has been conducted on Cutting Force and Chip Morphology under ambient and Cryogenic condition. From experimental data it can be clearly seen that increase of cutting force become more significant with higher cutting speeds for cryogenic cutting. This is due to a larger modulus of rubber and increased rigidity of rubber at lower temperatures leading to less workpiece material flow underneath the tool clearance surface which is very much beneficial in maintaining cutting stability and achieving a good machined surface finish. In contrast, the rake angle of the tool plays an important role in generating a smooth machined surface. Tools with a large rake angle produce a smooth surface with ribbon-like chips. Conversely, rough surfaces and discontinuous chips are generated with tools with a small rake angle.
