In one form the systems and methods include attaching an end effector to the industrial robot; (a) moving the industrial robot in a compliant way until a stylus of the end effector touches a point on the touchscreen; (b) recording a position of the stylus of the end effector in the industrial robot coordinate system when it touches the point of the touchscreen; (c) recording a position of the touch point on the touchscreen in the touchscreen coordinate system; and calculating a relation between the industrial robot coordinate system and the touchscreen coordinate system based on the at least three positions of the end effector stylus and the at least three positions of the touch points.

In a machine tool that performs threading, a thread-cutting startable area parallel to an X-axis of the machine tool is set based on a timing when a relative feed rate between a tool and a workpiece reaches a thread-cutting feed rate after the tool starts cutting feed. Then, movement of the tool in an X-axis direction is started first, and a rotation position of a spindle is monitored. When a thread-cutting start angle of the spindle is detected, cutting feed in a Z-axis direction of the tool is started if the tool travels in the thread-cutting startable area.
