Abstract: A method includes: (a) transferring a tool to where thread cutting is to start; (b) cutting threads in work with the tool; (c) performing tool deceleration along the Z-axis and acceleration along the X-axis during a predetermined acceleration/deceleration time Ta to retract the tool along the X-axis; and (d) returning the tool to a reference point. In Step (c), to shorten the incomplete thread portion, a command is issued concurrently with the start of the acceleration/deceleration time Ta to realize a pullout speed Ve along the X-axis that exceeds an allowable maximum speed Vmax to increase the acceleration along the X-axis. The speed command for moving the tool along the X-axis is maintained at the value of zero from the elapse of command time Te until the acceleration/deceleration time Ta expires to maintain the actual speed of the tool along the X-axis at or below the allowable maximum speed Vmax.

Abstract: The present invention provides a simple method of reducing an incomplete thread portion comprising the steps of: (a) transferring a tool in the direction of the X-axis to position the tool at the point where thread cutting is to be started; (b) transferring the tool in the direction of the Z-axis in synchronization with the rotation of the main spindle to cut threads in work; (c) performing a pullout operation by deceleration in the direction of the Z-axis and acceleration in the direction of the X-axis during a predetermined acceleration/deceleration time Ta so as to retract the tool in the direction of the X-axis; and (d) withdrawing the tool in the direction of the Z-axis to return the tool to the reference point of the thread cutting cycle.

Abstract: A cutting tool having a blade section on one end is mounted on a spindle of a cutting machine, and the blade section is contacted with a workpiece to perform planing of the workpiece into a desired shape. Because the tip of the blade section is disposed on the spindle axis, the position of the cutting edge is controlled by performing drive control of the X-axis and Y-axis of the spindle. Thus, the control of the cutting machine is simplified, and path errors resulting from synchronous control can be eliminated.

Abstract: It is strongly demanded that a stable thread machining process be attained by carrying out a thread machining operation while varying the rotational frequency of a spindle, and thereby restraining the occurrence of cutting chatter. According to the present invention, in which a thread machining process is carried out on the basis of a rotation of the spindle and a movement of a feed axis, the above-mentioned demand is met by executing the steps of determining a relative phase error of the spindle positions and feed axis during a thread machining operation, and determining a movement quantity of the feed axis on the basis of a pseudo spindle position set by error-compensating the quantity of the relative phase error with respect to the spindle position.
