I was looking through a tooling catalog for threading tools. In the catalog they said something about the canned threading cycles on a lathe doesnt make real good threads sometimes because of the depth of cut isn't deep enough or something.

One of the most critical capabilities of a lathe is it's ability to single-point thread. CNC threading extends this enormously by allowing an infinite number of.

It said that it is better to write a custom program for threading? Now im new to this stuff so I do not know what they are talking about. Anyone know what they are talking about and if you do can you give me an example of a custom threading program.

Thanks again. I was looking through a tooling catalog for threading tools.

Thanks again.From personal experience on a Haas CNC lathe there is nothing wrong with the threading cycles. As in all machining you may have to make minor adjustments to hit size. G92 will give you custom threading. Example.2'-12 thread.numbers may not be accurate but it's just for show. G92 X1.980 Z-3.00 F.0833 DEPTH OF FIRST CUT CAN BE AS HEAVY OR LIGHT AS YOU NEED X1.960 CAN MAKE CUT DEPTH WHAT EVER I WANT IN EACH X MOVE.THE IS THERE FOR THE FIRST PASSES TO ALLOW ME TO SKIP THEM IF I RERUN PART TO HIT SIZE,NOT NEEDED BUT HELPS ON DEEP THREADS X1.950 X1.940 X1.930 X1.920 X1.910 X1.9 X1.895 be careful on taking light cuts in a thread.sometimes you need a couple light passes for spring back.Other times it will cause chatter or shitty thread.you just have to give it a go and adjust from there.

X1.892 G00 X10. Z.03 M30 G76 can be custom to an extent.In the settings there are factors you can change to control how much it leaves for last pass and a few others,sorry I forget now because I have mine set and never muck with it much. G76 is like using the compound and slide to move the tool in at an angle and only cut on one side.G92 just goes straight in and cuts on both sides of tool. G76 A59 K.054 D.02 X1.892 Z-2.

F.0833 that's it,same thread as above just less punching of the buttons.On HAAS control every thing is needed in this sample to cut.The settings in the control cover all the other stuff.
