Abstract:
A positioning control method for determining a position of a workpiece and a tool of a machine tool using rapid traverse command for moving the tool and/or the workpiece to a predetermined position at a maximum speed and linear interpolation command for moving the tool and/or the workpiece while linearly interpolating, comprising the steps of:setting a comparison reference value according to a moveable range of the machine tool;detecting a command value of a rapid traverse by the rapid traverse command;comparing the comparison reference value and the command value;determining which one of the rapid traverse command and the linear interpolation command should be executed, wherein the rapid traverse command is executed when the command value is larger than the comparison reference value, the linear interpolation command is executed when the command value is smaller than the comparison reference value and either the rapid traverse command or the linear interpolation command is executed when the command value is equal to the comparison reference value.
