A carriage is moved in a direction including a Y axis component in order to move a turning process tool that is attached to a tool spindle along a horizontal line that is perpendicular to a Z axis, and thus, a turning process is carried out on a workpiece which is attached to a workpiece spindle.

Blade position registering apparatus

On a frame, a headstock and a tool rest are provided being free to relatively move so as to perform machining operations. The headstock is rotatably provided with spindle. The spindle is provided with a workpiece gripping means. One or more than one bar supporting means for movably supporting a bar stock in a predetermined feeding direction are provided at a predetermined position with respect to the spindle. A cutting means, for cutting the bar stock supported by the bar stock supporting means at a cutting position on the feeding direction side to the bar supporting means, is provided. A workpiece carrying means is provided being free to move relative to the headstock so as to deliver the workpiece produced by cutting of the bar stock with the cutting means to the workpiece gripping means of the spindle from the workpiece gripping means side to the spindle.

Numerically controlled machine tool and machining method thereof

A flexible manufacturing system which includes a stack yard, a machine tool and a stacker crane. In the stack yard, a pallet group, formed by stacking a number of pellets, is stored. The pallet group is transferred to a machine tool cell by the stacker crane. Each pallet has a memory, and data of the pallet itself and the member loaded on the pallet are memorized by the pallet. There are various kinds of members such as work-piece, tool and chuck jaw. These members are stored on exclusive pallets made for each kind of the member. Of the members, each tool and chuck jaw has its own memory and memorizes its own data. The data of all the memory can be read and written; therefore, the position of the pallet, tool and chuck jaw can be controlled at all times.

Flexible manufacturing system

A complex machine tool has a single frame having a chip collecting space at a center portion thereof, first and second spindle stocks on the frame, relatively free to move and drive in a Z axis direction and holding the chip collecting space therebetween, workpiece spindles on the spindle stocks free to rotate and drive and facing each other, and tool rests. The tool rests have turrets and can assume various kinds of movement. Complicated and varied types of machining can be performed combining the rotation control of the workpiece spindles and the spindle stocks.
