In this preliminary design study, we have made 10 design modification of a 5-axes multi-tasking machine, which has turning, milling, drilling, tapping, hobbing, and grinding. Furthermore we carried out static and dynamic structural analysis for all the design modifications by using ANSYS. From the analysis results, we could figure out a possible one among the design alternatives. But it is recommended to consider and review other possible machine layouts additionally at detail design stage because our machine having huge size and heavy weight of about 40 tons experiences large static deflection.

In this paper, dynamic analysis a spindle system for 5-axis multi-tasking machine by using ADROS, which is our own developed S/W for dynamic design analysis of rotor systems. As the result, the critical speed of our spindle system for 5-axis multi-tasking machine is above twice of the operating speed.
