As the end-effector of robot, the induction hardening tool is required to keep its orientations perpendicular to the fillets or chamfers of the mould at a distance during its uniform motion along the hardening trajectory. This trajectory consists of a group of central curves which are parametric curves on the corresponding chamfers or fillets and between two edges of every chamfer or fillet. The trajectory...
The span and length to diameter ratio of the large-scale crankshaft are big, and the structure and the distribution of crank pins are complex. Thus it is easier for crankshaft to generate biggish torsional deflection which finally influences the contour precision of the crank pin in tangential point tracing grinding. Based on the analyses of force and torsional deformation of the crankshaft under...
