Abstract
A simplified engine lathe simulator for junior level students in manufacturing practice has been developed. This simulator is a system consisting of a control unit having an operation handle in each 3 axes and PC. The cost to make the control unit is quite low and it is easy to construct the system. Almost all lathe operations including screw thread cutting, knurling and measuring the workpiece dimensions are possible on this simulator. The lathe work simulation was conducted for 220 students divided into 8 groups using 15 simulators. Questionnaire surveys to students showed that the practice using the simulator was effective to understand the lathe work and the operation technique.
