put a S code on the line before the live tooling tap cycle (g195) That is the place it gets the rpm for the cycle.

I agree with ProToZyKo.

try this

diameter x pi = circumference

circumference / 360 = distance per degree

feedrate / distance per degree = feedrate in degrees

That looks like chatter.check the rigidity of your work holding.maybe a screw jack under the part damping the vibration.it seems to be on the part where the vise isnt directly under it.I am just...

I really believe the tool path is what will make this successful.not preaching to choir or underestimating you but I believe line by line programming on this application is best to get desired...

drill a 375 hole to z-3.990 w a twist drill using a spot drill first.

position the first x position to -.05 from where center of.375 hole is to have room to turn on cutter comp for .500 hole...y...

Is the length of cut on the end mill just over 4 as well
??

Is this fanuc control? Give me the print dimensions of the hole and list the tools you have.i believe I can help. ..

ok.i put an edge finder in a radial tool and find center of a dowel in the chuck and hit part zero set on the y axis.i believe that is how you set a "g54" y0.tjays how I do it and my "milled"...

I know this is an old thread but have you figured it out? I just had success programming a thread mill but using Cartesian to polar coordinate transformation on my fanuc control wouldn't work.use the...

I realize that.I was just putting the info here because I know from my own experience that cnczone is a reference for some people.I don't believe in too much reference material.Thanks though

you can use axis mapping if you have a fourth axis.put the a axis flat on the table and use a G107 a0 x0.it will then convert all the x moves to an "A" move and therefore keep the letters engraving...

no it dont look like the ones i like to use

is the ramp distance the circumference of the tool path circle maybe?

I cant answer that, but i only use P Q U W D F no I or K.This has worked fine for me for years.Id like to know when they would come in handy though.

Try to switch the g2/g3 in your program first to make sure thats not why its alarming out to begin with

That was a code I copied off this thread of discussion.I see there is no height offset callup.here is how I would have written it.I am assuming those generic motions are what your looking for.this...

maybe try to put the g19 in its own line before the g2?...

If your machine has spindle orientation option you could put a broach w a round shank in the machine orientate the spindle to line up with your area of the square corner,and move z down and step,over...

Not a problem. I just prefer ijk method.It may in fact work with the r only.idk for sure.ive been told to always use ijk but that may just be as good as r.good luck

The center of the radius is the center of the pipe.if the top is z0 and your at z-1.875, the center of the arc in z is -2.9375 below where your tool is so k-2.9375 should be correct.arcing from...

Nevermind.I seen wherr you already said the od size.ill get right back to you

I wasnt thinking correctly.the j is center of arc from where your at (incremental) .same as k.if your arcing from were the tool is at same z as center of the arc,k is 0 or just leave it out.what is...

you need g02 g03 in there instead of g01 on the lines with the plane change code (g19). i dont know off the top of my head which will arc to z positive.try it above the part first.

if your at x1.0...

Use g19 to arc in yz axis.use ijk when programming radius is my suggestion not R...trust me.k is center of arc in
Z axis, j is center of arc in y axis.

follow the program on the screen as it is running.get a cheat sheet with all the m and g codes on the and try to grasp how the machine movements relate to them.that will move you along a little but...

i would try finishing the face feeding down from big dia to small dia,then reposition tool and come back and finish the od turn.id say leave about .015 for od finish and .002 for face finish.feed...
