Once applied, the program header is displayed. Figure 6-9 Program header, example 1 – Work step editor The program has now been created as the basis for further machining steps. It has a name (in the blue bar), a program header (pictogram "P") and a program end (pictogram "END"). The individual machining steps and contours are stored in the program one beneath the other. The program is subsequently executed from top to bottom. You can open the program header again at any time to make changes or check the values. Retract position pattern The position pattern can be set to "Optimized" ( = time-optimized traversing paths) or "To retraction plane". Optimized retraction To retraction (standard) The tool traverses over the workpiece at the safety distance The tool back to the retraction plane and is fed in to the new position.
Enter the following values for the re-machining of the pocket in the screen form: Field Value Selection via toggle key Notes F 0.08 mm/tooth X V 150 m/min X Machining Base X UXY The previously entered allowance for roughing must remain set for the values in the "Finishing allowance plane (UXY)" and "Finishing allowance depth (UZ)" fields. This value is important for automatic calculation of the traversing paths. Figure 8-24 Finishing a pocket Accept the entered values. Select the "Pocket" softkey.

Thread milling Operating sequences Figure 9-58 Thread milling Select the "Mill." softkey. Select the "Thread milling" softkey. Open the tool list and select "THREADCUTTER". Apply the tool to the program. Mill the thread from top to bottom. The "THREADCUTTER" is used for this (F 0.08 mm/tooth, v 150 m/min and pitch 2 mm). A right thread is to be milled to Z-23 (absolute dimension). Due to the overtravel of 3 mm, the thread is always milled cleanly down to the workpiece lower edge even if the lowest tooth is slightly worn. The help screens are very useful for the Compare your entries with the figure below: Figure 9-59 Thread milling Accept the entered values.
