Abstract: A machine tool and a control method therefor providing an improved machining accuracy even when a numerical control and electronic cam control coexist. The CPU determines the moving position of the workpiece, the tool, and the drilling tool according to the command from each channel machining sequence storage portion, and outputs the determined position as a command signal in response to the pulse signal generated at the pulse signal generating circuit. The workpiece, the tool, and the drilling tool are thereby electronic cam controlled. The CPU also determines the moving position of the workpiece and the tool according to the command from each channel machining sequence storage portion, and outputs the determined position as a command signal in response to the divided timing signal generated at the divided timing signal generating circuit. The workpiece and the tool are thereby numerically controlled.

Abstract: The movement position of the roughing tool is calculated, in S109, by adding the finishing allowance to the movement position of the finishing tool so that the path of the roughing tool is shifted in the direction perpendicular to the rotation center axis of the main spindle rotation motor from the path of the finishing tool by the finishing allowance. Then, a gap between the movement position of the roughing tool in the direction of the rotation center axis of the main spindle rotation motor and the workpiece W is calculated, and when the gap is not larger than a predetermined value G, in S113, the movement position of the roughing tool is corrected in the direction perpendicular to the rotation center axis of the main spindle rotation motor so that the roughing tool does not cut in the inside of the finishing portion of the workpiece. The movement position of the roughing tool is corrected so that the movement speed of the roughing tool in the direction perpendicular to the rotation center axis of the main spindle rotation motor is a predetermined value.

Abstract: In cutting a high-accuracy thread, a control unit (CPU) uses a first position data calculation program to determine the moving positions of a workpiece and tool every predetermined rotational angle of a spindle rotating motor. The control unit stores the determined moving positions of the workpiece and tool in a first position data table memory, and outputs the determined moving positions as a workpiece position instruction signal and tool position instruction signal to a workpiece feed control circuit and tool feed control circuit every predetermined rotation. In cutting a low-accuracy thread, the control unit uses a second position data calculation program to determine the moving positions of the workpiece and tool every predetermined time interval. The control unit stores the determined moving positions of the workpiece and tool in a second position data table memory, and outputs the determined moving positions as a workpiece position instruction signal and tool position instruction signal to the workpiece feed control circuit and tool feed control circuit every predetermined time interval.
