Abstract:
OBJECTIVE:To overcome the shortcoming of manual method,computer-aided manufacturing (CAM) system of prosthetic socket is applied to improve socket's quality and processing efficiency,which also reduces the demand of operator's knowledge and experience.METHODS:Prosthetic socket CAM system was discussed based on an advanced manufacture technology,and the hardware and software were designed.The advanced manufacture platform was composed of an industrial personal computer (IPC),a motion control card,four sets of Panasonic digital AC servo control system,four lead screw guides,two spindle motor of milling cutter,a transducer,two switching power supply,limit switch and proximity switch.The software of prosthetic socket CAM system mainly included three function modules:parameter setting,machine testing and beginning processing.Through adjusting command pulse's input and driver's coefficient,the motor worked at different speeds.RESULTS:The result of experiment demonstrated that maximum rotational speed restriction was applied to protect the motor,and the motor could work very smoothly without vibration in very low speed.It was suitable for manufacture prosthetic sockets,and could manufacture the high quality prosthetic socket to satisfy the requirements of amputee.CONCLUSION:Prosthetic socket CAM system based on the advanced manufacture platform can overcome the shortcoming of traditional manual method,ensure product quality,and reduce the cost.The protracted experience of certified prosthetist was incorporated into the design program to reduce the demand of manipulator's knowledge and experience,increase the one-time success rate of manufacture prosthetic sockets,and improve the quality uncertainty of sockets.It can change the backward production mode of designing,measuring,taking model,and modifying model which depends on handwork.
