The Design and Analysis of Saw-Milling Working Head for Special Shaped Stone

Abstract:

For a new type of saw-milling composite work-head, using the finite element method and modal analysis tests to get the dynamic characteristics analysis of the system. We have made dynamic parameters analyses which are mode shape, natural frequency and damping ratio of the whole machine and the piece structure of work-head, and identified the weak links of the machine. The research shows that: the composite work-head’ weaknesses are in the sliding saddle joint, and the vibration instability trend would drive the whole machine; the dynamic stiffness of spindle is lower in the low frequency band, and it causes a certain influence on the machining accuracy.
