Cover Story: Construction of renewable energy power stations and offshore platforms greatly increases the demand for heavy-duty multitasking turning machines. Evaluations of the structure behaviors are very important at the design phase to ensure the machine tool meets the desired requirements. This study aimed to realize how the turning machine will behave when it carries a larger and long workpiece. The design issue was focused on analyzing structure rigidity against the bending deformation of a workpiece and vibration response characteristics during low-speed cutting via the finite element approach. We believe the results with the technologies involved in this study can help the machine designer to effectively evaluate the characteristics of the machine before prototyping. View this paper
