Milling a tapered inside thread

Milling a tapered inside thread

NC3170

NC program for milling a tapered internal thread. This program is arranged so that first another program is called to pre-mill the tapered hole. At the beginning of this called program you have to define all required parameters from which the control then calculates and executes the tool paths to manufacture the tapered hole. After the program call in the main program, you also have to define the parameters required for milling the thread. The control then uses these values to calculate the tool path for the thread. This path consists of linear segments for which the control calculates the X, Y and Z coordinates of each of the end points and then moves to them. Machining is always in the positive Z direction so that you can use the rotational direction of machining to specify whether the thread is left-handed or right-handed.
