Reconfigurable modular machine tools are major components of reconfigurable manufacturing systems and the design method is the key to achieve reconfigurable manufacturing processes.In order to respond to the changing needs of different machining processes in time,a modular workbench for reconfigurable machine tools was proposed,and the workbench could be switched quickly.At the same time,an automatic machining operation flow was designed for the worktable,by which the problem that the hydraulic clamp might be wounded and broken due to the single-direction rotation of the worktable could be solved,so that the PLC control and the hydraulic transmission could be fully integrated in the automatic production.In the workbench system,PLC was used to control the transmission of hydraulic components,which in turn drove the movement of relevant mechanical structure,and automatic cycle processing could be realized without failure and manual intervention.
