摘要： PROBLEM TO BE SOLVED: To shorten the required feed time when a tool is sent from the start point of a preceding actual working route to the end point of a succeeding actual working route as much as possible, in a method for controlling the feed speed at the time of sending a tool from the preceding actual working route to the succeeding actual working route not on the extension line through a free working route by a working machine so as to work a work with the tool. SOLUTION: Y direction acceleration and deceleration for increasing the Y direction components in a direction perpendicular to both of a preceding cutting operation block A-B and a succeeding cutting operation block D-E of the feed speed between the start point B and end point D of a picking operation block B-C-D and then reducing it are performed. Also, parallelly to that, second direction acceleration and deceleration for reducing and then increasing the X direction components in the direction parallel to the preceding and succeeding cutting operation blocks of the feed speed are performed with a point A' set in the middle of the preceding cutting operation block as a deceleration start point and the point E' set in the middle of the succeeding cutting operation block as an acceleration end point.

摘要： PROBLEM TO BE SOLVED: To reduce the cost by enhancing the yield of an insulating material without sacrificing the productivity.
SOLUTION: A pair of interphase parts 10 and 11 opposing trough a distance shorter than the axial length of a stator core, and parts 20 and 20 having nonlinear parts, i.e., bends 22 and 22, at least partially and coupling the interphase parts 10 and 11 integrally are formed integrally by cutting off the unnecessary parts of the elastically deformable insulating material. Area of the unnecessary parts to be cut off and wasted is reduced as the distance between the interphase parts 10 and 11 is shortened. When the interphase insulating paper is fixed to the stator, it is inserted into the slot of the stator core under such a state as the bends 22 and 22 at the coupling parts 20 and 20 are elongated linearly through elastic deformation, and the interphase parts 10 and 11 are arranged between the coils of different phase at respective coil end parts.
