The effect of cutting tool insert geometry has significant role for surface finish in turning operation. There are many different types of tool inserts with different tool insert geometry are used in turning operation. This paper present a logical procedure to select best tool insert from alternative tool inserts for better surface finish in turning operation. The procedure based on three well ...

CNC machining is the leading subtractive manufacturing technology. Although it in use since decades, far from fully solved and still a rich source for challenging problems geometric computing. We demonstrate this at hand of 5-axis freeform surfaces, where degrees freedom selecting moving cutting tool allow one to adapt motion optimally surface be produced. aim high-quality finish, thereby reduc...

Geometrical inaccuracy of sheet metal parts due to springback are the reason for considerable efforts in the tool and process development. Numerous studies have been carried out in order to find the optimum process parameters and tool geometry so that the resulted parts to be within tolerances. In the present paper, the finite element method coupled to the neural network method are used to get ...
