| Abstract | ||||
| This paper describes the static and dynamic behaviour of a proposed tooling system, for vertical-spindle surface grinding machine using, as Joint modules, the curvic coupling as well as a taper joint of the ratio 7/ 24. The experimental results obtained were compared with that of the conventional mounting method of flange type (flat joint). Through this work, the effects of the joint geometrical features, joint tightening torque, and loading condition on the static and dynamic behaviour were investigated. The most important finding is that the curvic coupling as a joint module for the proposed tooling system, has better static and dynamic behaviour than the corresponding taper and flat joints. Improvement rates of about 30%-60% in the static bending stiffness, about 17%-50% in the damping capacity, and about 9% in the natural frequency, have been observed . In addition, the tightening torque considerably affects the static and dynamic behaviour of the tooling system, particularly when the system is subjected to the vertical loading condition. | ||||
