The tool geometry such as rake angles and cutting edge inclination angles play significant roles in determining machining performance. The task of selecting cutting tool inserts and cutting conditions is traditionally carried out on the basis of the experience of process planners with the help of data from machining handbooks and tool catalogues. This situation urges the need for development of some intelligent tooling system to reduce these inefficiencies for optimum economic and technological machining performance. A model of turning tool mechanism having the function of controllability in changing the tool inclination angle and tool approach angle is described. The mechanism is realized through the use of three specific slopes which work simultaneously to compensate the tool tip deviation due to the change of inclination angles so that the tool tip always stays at working point in space. Based on the ‘classical’ oblique cutting operation, analytically simulated prediction of the tangential cutting forces were presented with MATLAB software.
