Tool nose radius compensation for CNC lathes.

tool nose radius compensation chart download

Whenever the insert of a tool must machine with over 90 degrees of its cutting edge is probably a good time to think about using tool nose radius compensation for sizing purposes. Most machine tool computers have this built into the controllers. The turning inserts nomenclature is a list of some letters and numbers, but. I hope my new seat of Dolphin for the lathe will help alleviate some of my woes. Like some of you have said, it seems like way too much work to manually write code without cutter comp. Too much effort for absolutely nothing, when the control does it flawlessly. I assume W is the finish allowance for Z in the G71 Cycle.

Yes, I know it can be quirky sometimes. Are you on the right side? In the majority of cases when cutting a chamfer, one of the two axes is offset at the Start, and the second of the two axes is offset at the End as shown in the attached picture. The G71 and G72 cycle I virtually always utilize and try as hard as I can to get away from longhanding a rough cycle. Calculate mill side wall finish based on tool diameter, cutting edges, and feed rate. Sorry about the confusion here as i am still learning. Get thread pitch, major, minor, root radius, helix angle, and more for 60° threads. So the starting X-value would be.

The guy that has done most of the programming for the past 10 years is the one that doesn't like cutter comp, therfore the whole shop doesn't use it. The far left radio button on the bottom left of the parameters page. For example, with G3 you must add the tool nose radius to the radius of the arc you are programming and also adjust the start point and end point. In your above scenario, you can't then use the profile definition of the G71 cycle with G70. Correspondingly, I'd rather be able to calculate values for the exact angle.

Then memorize the X-incremental move for the different R-values you normally use. Don't forget about fanuc X negative lathes. How to apply it to Z-10 is as e. Now go to the lower left corner and in the compensation window click the circle second from the left. I guess it takes me longer than most and once I have done it for a while I'll get used to it.

I really dont get this part. I use control comp exclusively. Obviously there is no compensation needed for the Z axis but you do need to calculate tool nose radius compensation for the X axis if you want to make an accurate angle. Straighten me out if you can Although I can certainly see the benefits of using tip radius comp on the lathe, I tend not to, because of confusion between the tool touch off point and the true center of radius of the tool tip. C ok i think i understand now. That would be totally bad if they were that way too.

If come from X0 side, to make taper from x9 to x10 by 60° : G1 X8. It answered one of my questions about whether it was standard practice to make edits at the machine vs. While I can certainly do this and write the microcode behind it in the control, I see no reason to do things the hard way. I'm looking for short cuts on how to remember, i. Accordingly, if the control uses Diameter Programming for the X axis some machines use Radius Programming , Xc is multiplied by 2 and the result added or subtracted, depending on the direction of compensation required, to the diameter coordinate involved. I've never tried to figure an easy way to do the math.

How to program a CNC lathe without a cutter comp

This solution saves you time and errors, not to mention that it makes you look like an expert. And I did not mention it because I treat the G70 cycle not only the most useless cycle ever existed, but also as the root cause of a lot of headaches, inconsistencies, garbage parts, confusion, murder, mayhem, mass hysteria, dogs and cats living together. Not talking about G41 and G42. Much, much easier to add deduct a fixed amount to a few Z coords than to go through the math exercise shown above. Next month we discuss how this value is used in programming. Mmm I dunno the jury is out on this one.

For finishing tough, they do use comp and I think they do it without quirks, or at least with predictable quirks. I hope this is what you are looking for. If you want all your tools comped to the center of the radius, make a new tool library, change the comp to center and save the tool to the library. Tools can be touched off on presetters or workpieces readily, and if the right insert is in the holder, radius comp errors are eliminated. Then how would you know what that amount needs to be without some form of calculation using an algorithm such as shown below, or in Post 5 by Mikiemus.

Angles are fairly simple, but annoying to do. General Turning Insert Nomenclature Shape The first letter in general turning insert nomenclature tells us about the general turning insert shape, turning inserts shape codes are like C, D, K, R, S, T, V, W. Turning movement from left to right insideside, always G42. I would suggest photocopying this chart and keeping one on each machine if that is how you are programming. Instead of adjusting wear offsets to hold size in this kind of application, the tool nose radius compensation offset commonly specified in the offset table under the R register will be changed.
