Modification Of The Surface

The loads acting on a workpiece during machining processes determine the modification of the surface of the final workpiece and, thus, its functional properties. In this work, a method that uses thermocouples to measure the temperature in precision fly-cutting machining with high spatial and temporal resolution is presented. Experiments were conducted for various materials and machining parameters. We compare experimental measurement data with results from modern and advanced machining process simulation and find a good match between experimental and simulation results. Therefore, the simulation is validated by experimental data and can be used to calculate realistic internal loads of machining processes.

Simulation Results

Aerospace super alloy Inconel 718 is difficult to process through conventional machining operation. Alloys with high strength at high temperatures and high strain hardening, high chemical affinity (towards tool material, and Co binder) etc. impose adverse effects towards smooth machining. Poor thermal conductivity of Inconel 718 promotes excessive temperature rise at the chip-tool interface which causes rapid tool wear, and degraded surface integrity of the end product. Adequate understanding of machining process phenomena along with precise control of machining parameters may yield satisfactory result. Trial, and error experimentation is indeed uneconomical; hence, in the present reporting, Finite Element (FE) based numerical simulation is attempted to model machining responses in the extent of cutting force, tool-tip temperature, depth of flank wear progression, chip-tool contact length, and finally, chip reduction coefficient. Simulation results are verified through experimental tests. Simulation results are found in good agreement with experimental results. Therefore, simulation results can reliably be used as an alternative instead of actual experimental effort.
