Abstract
During the process of Milling for v cut Slot minor Cracks are generated in fork Surface, which during induction hardening process converts in to deep cracks and can only be detected during the non-destructive testing like MPI. This leads to higher rejection ratio and incur financial and material losses. The existing design of fork is heavy and not compact which leads to problems during assembly and leads to bending in rails. This necessitates a new design of fork is compact and light weight. The aim of this research is to determine the contribution of v cut slot in forks. The second design is modelled without v slot and analysed under the same boundary conditions. The experimental tests using driveline rig is also performed and on Road Vehicle Testing is verified with simulation results.
