摘要

PROBLEM TO BE SOLVED: To provide a working assisting device capable of easily moving a tool along a target track without dropping the working efficiency excessively.;SOLUTION: The working assisting device is to assist the operator in performing the operation for a workpiece rotating, whereby the tool is moved along the target track set on the workpiece previously. The device comprises: a workpiece rotating device to rotate the workpiece round a rotary shaft; a tool moving device to change the position and direction of the tool in accordance with the operating force applied by the operator; a tool position sensing means to sense the position of the tool; a tool direction sensing means to sense the direction of the tool; and a controlling means to control the workpiece rotating device in such a manner as decreasing the angular velocity of the workpiece rotating device with longer distance from the sensed tool position to the rotary shaft and also decreasing the angular velocity of the workpiece rotating device with greater angle formed between the counter-moving direction of the workpiece in the sensed tool position and the sensed direction of the tool.;COPYRIGHT: (C)2008,JPO&INPIT
