The processing material's shape data is obtained by measuring the three-dimensional shape of the processing material W by the three-dimensional measuring device 45, the machine's shape data defining the three-dimensional shape of the machine side including the main shaft head provided with the processing tool and the tool holder attached thereto is obtained, and whether the coordinate position of said processing material given by said processing material's shape data is in the space to be occupied by the machine given by said machine's shape data or not is determined at the relative movement position between the main shaft head (43) and the work table (35) by the execution of the processing program by the arithmetic processing by means of an arithmetic processing means, and when the coordinate position of the processing material W is in the space to be occupied by the machine, it is determined that the processing material W and the machine interfere with each other.

A spindle 51 capable of controlling quantitatively the rotational angle around the center axial line itself is mounted with a turning tool 50; the spindle 51 and a workpiece are allowed to be relatively dislocated by an axial control along at least a plane perpendicular to the rotation axial line of the spindle 51 in such a manner that the relative movement locus L of the spindle center Cs to the workpiece conforms to a geometry to be machined and a required front rake angle .beta. is set, thereby allowing a mutual interpolation motion between the spindle and the workpiece to be performed; and the rotational angle of the spindle 51 is synchronously controlled with a required interrelation to the above-mentioned axial control, whereby the direction of the cutting edge of the turning tool 50 to the machined face of the workpiece is kept at a required direction at the full rotational angle position of the spindle 50 with the required front rake angle .beta., and the direction of the cutting edge of the turning tool 50 to the machined face of the workpiece W is kept at a required direction, and then the workpiece W is machined into a geometry determined by the interpolation locus L due to the above-mentioned mutual interpolation motion.

A pre-preg pre-cut tape 20 is made by the steps of converting the forms of a pre-preg to be cut into co-ordinates on a pre-preg tape 2 from the data on the form of lamination and the condition of lamination to form the data on the form to be cut, forming the data on the forms of unnecessary portions showing the forms of the unnecessary portions 4 from the data on the forms to be cut, forming the data on division for dividing the forms of the unnecessary portions into the forms of (a) to (f) removable from a mold releasing paper, and forming the data on the direction of removal for showing the direction of removing the unnecessary portions of (a) to (f) divided on the basis of the data on division, whereby the unnecessary portions 4 are removed on the basis of such data.
