PURPOSE: To enhance working precision by carrying a formwork along the carrier path of a working part, positioning the formwork in the carrier direction and the direction orthogonal to the carrier direction, holding the same, moving a cutter and a drill in the carrier direction and the direction orthogonal to the carrier direction and the vertical direction and displacing the cutter in a horizontal attitude and a vertical attitude.
CONSTITUTION: A formwork 1 is fed to the carrier path 10 of a working part by a carrier path 13 and a feed carrier path 11. The formwork 1 is carried by the carrier path 10 of the working part and abuts against a work stopper and is positioned in the direction of X-axis and also sent to the carrier path 10 of the working part and actuation is stopped. The side wall of the formwork 1 is pushed by moving the pushing member by a cylinder for movement of a work pushing mechanism 21 The side wall 4 is pushes to the stopper 20 and formwork 1 is positioned in the direction of Y-axis and held so as to be not moved. An electric motor 65 for moving *-axis is driven to move a first and second moving frames 26, 27 in the direction of X-axis. Moreover an electric motor 72 for moving Y-axis is driven to move the respective moving bodies to Y-axis. An electric motor for moving Z-axis is moved in the direction of Z-axis.
