Abstract The present study proposes an advanced force display control system for a surgical training simulator with virtual reality. In oral and orthopedic surgeries, surgeon uses chisel mallet chiseling cutting hard tissue. To enable the representation of sensation operation in simulator, device has been constructed ball-screw mechanism to obtain high stiffness. addition, two-degrees-of-freedo...
