Training Simulator for Manual Lathe Operation Using Motion Capture
Nobuyoshi Hashimoto · Journal of the Japan Society for Precision Engineering · 2019
Training systems for manual machine tools using virtual reality have been developed for high safety and economy. Using these systems, a trainee can safely work on virtual machines to manipulate input interfaces modeled after devices in real-world machines. However, a trainee cannot completely learn how to use the target machine because the interface lacks all the necessary devices. Because safety is ensured even if the trainee performs dangerous actions, these virtual systems cannot teach safety measure. Therefore, after training with these systems, a trainee needs instructors when operating actual machines. This study describes a training system that does not require instructors. By training with the proposed system, a trainee can safely work on virtual machines as the input interface to manipulate the actual lathe. This system constantly monitors the position of all operating devices, handles and levers on the actual lathe, and the user’s body parts (the head, both hands and upper body of the trainee) by motion capture. The behavior of the virtual lathe and the cutting of the virtual workpiece are simulated from the manipulated variables. This system can detect whether the trainee is in danger from the movement of his body parts.
