5.4.6.3 Thread shaving after thread cutting

Functionality

At the end of each thread cutting operation, you can choose to continue machining the

thread, i.e., to perform shaving. Thread shaving can be performed either with or without an

additional infeed, in which case it is merely a "smoothing cut".

Operating sequences

The following query is displayed at the thread end:

"Should the threads be recut?"

Softkeys

If no thread recut is necessary, confirm the prompt with "Cancel".

To perform a thread recut, confirm with "OK".

You can then select the infeed type using the following softkeys:

Pressing this softkey means that an additional cut is executed at the same infeed depth as

the previous cut when you press <NC-Start> (additional "thread smoothing").

When this softkey is selected, the tool will be fed in by the amount entered in the "Val. f.

Feed" field next time the NC Start key is pressed. The thread is machined accordingly in the

next cut.

This softkey is used to enter the infeed value for subsequent machining. On pressing the

key, the corresponding entry field (already on dark background) is displayed in the screen

form shown below to enable you to enter the value.

Press the <INPUT> key as usual to accept the value.

Figure 5-43 Enter infeed

After pressing the "With Feed" or "Without Feed" softkey, press NC Start to start machining

an additional cut.

If you do not wish to do this, exit the "Execute Thread" screen by selecting softkey "Abort"

without executing an NC start.
