Abstract: A cutting tool for a machine tool is provided in order to cut an inside corner of a workpiece. The cutting tool has at least one cutting edge formed on its bottom. In operation, the cutting tool is rotated by the machine tool. Further, both cutting tool and workpiece move relatively to each other in accordance with the rotating angle of the cutting tool so that the cutting tool has its outer end describing a moving track in agreement with the contour of an inside corner of the workpiece. The cutting tool further moves along the direction of a rotating axis of the cutting tool in rotation.

Abstract: A profile processing method and a processing machine therefor which can obtain a good finish surface accuracy in all the carving surfaces and curb the decrease in tool's life are provided.More specifically, an end mill is first moved along an outermost side of an annular groove in carving the annular groove to a work. Consequently, the end mill is gradually moved to inside to be moved and carve along the annular groove. When the outermost side of the annular groove is carved, the movement path of the end mill is selected so that the outermost side is down-cut (counterclockwise in FIG. 5). When further inner side is carved, the movement path of the end mill is selected so that the direction of the relative movement path is opposite to the direction of the relative movement path when the outermost side is carved, in other words, the carved surfaces are down-cut by the end mill.

Less effective short-distance rapid traverse command is converted to the linear interpolation command, thus speeding up positioning control to make an entire processing of the workpiece faster.

Abstract: The invention relates to improvements in a tilting mechanism for a saddle swivel head for a double housing type machine tool. The saddle swivel head 13 is provided at the sides thereof in the tilting direction with hydraulic cylinders 18R, 18L, to which is connected a hydraulic piping system 19 for giving swivel balancing pressures and back pressures when the swivel head 13 is tilted by a predetermined angle by a tilting driving mechanism. The saddle swivel head 13 is tilted while providing swivel balancing pressures to the hydraulic cylinders 18R, 18L, and after tilting the head by the predetermined angle, back pressures are applied to the hydraulic cylinders 18R, 18L to compensate for a tilting moment of the saddle swivel head 13.
