Simple Peck Tapping Using a G84 Tapping Cycle – Haas Automation Tip of the Day

Hello and welcome to this Haas Tip of the Day. Right now we're going to show you how to peck tap using our G84 tapping cycle. When we say peck tapping we just mean that we're going to tap a little bit at a time until our full z-depth is reached. Now if you're not too sure about G84 tapping cycles in general we've made a couple other videos that go into that topic in depth. One for those that work in inch mode and another for those that work in metric mode so be sure to check those out. Before we can peck tap we have to turn a setting on at the control. Setting 133 repeat rigid tapping needs to be set to on. When repeat rigid tapping is set to on the spindle orients each time before tapping. This allows us to tap the same hole over and over again at increasing z-depths. So why don't we leave setting 133 on all the time? Well it's because it orients the tap each time before making that hole and that orientation takes some small amount of time. If you're not going to peck tap there's no reason to make your cycle times longer even by that small amount. Now each time we command an x or y location while in our modal G84 tapping cycle the control is going to tap a hole. Let's look at our code. On our G84 line we're going to tap a hole to z-0.5 at x0, y0. Next we're going to tap a hole again at x0, y0 this time to a depth of z-1 inch. At the next xy location which is still at x0, y0 we're going to tap a hole to z-1.5. By commanding the exact location that we're at over and over again with increasing z-depths we peck tap. Now we're still inside the G84 can cycle so if we want to tap a second hole all we have to do is command a new xy location. I'm going to type in x1 inch z-0.5. Now instead of tapping at x0, y0 it's going to tap at x1, y0 to a depth of z-0.5. To peck tap I'm going to enter x1 inch z-1 then x1 inch z-1.5. We'll continue this in half inch increments until we reach that z-2.5 depth. Well that's it. We wrote a program that peck taps two holes to a final z-depth in half inch increments by using setting 133. Now for those G84 videos that we talked about click on the bonus content at the end.
