摘要： PURPOSE: To conduct the machining of high productivity at a small cost increase by using the NC lathe of two main spindles and one back main spindle. CONSTITUTION: In regard to two main spindles for front machining, one back main spindle is used alternately, and by means of a first main spindle and a second main spindle, the same machining is conducted by shifting machining processes 1 and 2 by a half cycle, and as soon as the machining is finished, a work is moved to the back main spindle, and at the machining process 3 of the back main spindle side, the same back machining is conducted in regard to works received from either main spindle, and by this, parts of one kind can be machined at two times the machining efficiency (equal to the case of the conventional NC lathe of two main spindles and two back main spindles being used) of the case of one spindle. In this instance, the tool layouts of first and second tool rests are differed, and machining is carried out by exchanging the combinations with first and second main spindles at the first half and the second half.

摘要： PURPOSE:To obviate a control shaft to be exclusively used for the robot by designating the robot hand action and/or operation by the description of the coordinate positions or the like described in the sub-program of the program to be selected by the specified command code. CONSTITUTION:An NC program is inserted in an arbitrary position of the main program for machining in the G-code form. When the specified G-code is read, a numerical control device 11 of a numerically controlled machine tool judges that the read one is the specified G-code to operate a robot hand 7. Then, the sub-program to be designated by this specified G-code is read. Writing of the numerical values in the page where the coordinate positions or the like of this sub-program are described is executed by the teaching where the program is prepared by actually moving the robot hand 7, or inputting the numerical values from an inputting device of the numerical control device 11.

摘要： PROBLEM TO BE SOLVED: To control movement of a motor to move a tool for threading by adjusting it at an optimal adjusting value in threading work at the time of the threading work. SOLUTION: The optimal adjusting value of each of the motors to drive a spindle and a tool rest is previously found and is stored in a ROM 8 in a control unit or in an outside memory device 5 as a file for threading of a variable data at the time of the threading work by an NC machine tool. Thereafter, a variable data in a RAM 9 to use for adjustment of each of the motors by a program in practice is replaced by reading the previously stored variable data in the file for threading from the ROM 8 or the outside memory device 5 by a CPU 7.

摘要： PROBLEM TO BE SOLVED: To prevent a bar material from swinging by deflecting by using a sevomotor as a motor for a material feeder and a motor to move a main spindle, and outputting a command to impart constant torque to the motor for a material feeder so as to absorb play of a transmitting means when the respective motors are synchronously driven. SOLUTION: A main spindle 3 of an NC automatic lathe 1 is moved in the main spindle axis direction by a motor 5 to move a main spindle, and a bar material 2 is supplied by inserting the main spindle 3. A bar material supply device 8 is constituted so that a feeding bar 21 having a finger chuck 20 to grip the rear end of the bar material 2 is moved by a chain conveyor 22 driven by a motor 26 for a material feeder. In this case, the motor 26 for a material feeder and the motor 5 to move a main spindle respectively use a sevomotor, and are controlled so that a moving command to synchronously drive them is outputted to the respective motors 5 and 26 from a control device and a constant torque command is imparted to the motor 26 for a material feeder so as to absorb play such as looseness of the cain conveyor 22.

摘要： PURPOSE: To make continuous machining possible even in case of the occurrence of abnormality for shortening a time when an operation rate is zero by, when a part of one having a plurality among spindles and tool posts becomes partially nonusable, carrying out the machining through a backup machining using remaining usable spindles and tool posts. CONSTITUTION: During usual machining on a NC lathe, the same part is machined on the first and the second spindle side as it is shifted as much as a half cycle. In the case where the second spindle can not be used on account of the occurrence of abnormality, the first backup machining is carried out for machining a workpiece only on the first spindle side. In the case where the first spindle can not be used on account of the occurrence of abnormality, the second backup machining is carried out for machining the workpiece only on the second spindle side. In addition to that, even in case where abnormality occurs on the first or the second tool post, the backup machining can be carried out by attaching the whole tools required for machining only to the tool post on one side.
