    Default Peck Tapping in BobCAD ?

    Hey guys,

    Running Bobcad V28. The does a lot hole tapping on the Haas VF3-YT50. Material is 304SS. Is it possible to Peck Tap in Bobcad? I don't see an option for it like there is for drilling. I know the Haas is capable of it by turning on setting 133. This makes the spindle orient each time it enters the hole.

    Here is a snip of the code: (It's just doing a single depth) Would prefer multiple pecks to clear the hole out of chips.

    (TOOL #10 Badger UNC 5/8-11 Hand Tap)
    N917 T10 M06
    N919 T13
    N921 G90 G54 X1.5 Y2.1275 S98 M03
    N923 G43 H10 D10 Z1. M08
    N925 G00 Z-0.2
    N927 G95
    N929 G84 G99 X1.5 Y2.1275 Z-1.3506 R-0.3 F0.0909
    N931 G80
    N933 G94
    N935 G00 Z-0.2
    N937 Z1.


    In the Haas example on Youtube, they are showing multiple tap pecks.

    X0 Z-1. ;
    X0 Z-1.5 ;
    X0 Z-2. ;
    X0 Z-2.5 ;


    Any ideas?

    Thank you.

    If BobCAD doesn't support peck tapping for some reason, looks like I will have to Post the code and make the entries manually. Here is a better description of what peck tapping looks like. Taken from the Haas video.

    Peck tapping is not an in the box feature for the software, you could write a script to post code like the example above. Using the ADV posting tab the software api and a custom script you can format the code to do just about anything...

    We don't do much tapping, but below is another verified way to program with peck. The program is for a 304SS manifold. Bobcad may not have an option for peck tapping, but this is easy simple copy and paste. Running a Haas VF-3SSYT with Next Gen control here. Here's the peck portion of the program:
