has it been heat treated? If so, to what?

I'm curious as to how the backplot/verify time compares to the actual cycle time?

this is a quick code at those values feed and speed incorrect

 

T77 M6

G0 G90 G54 X5. Y30. S1577 M3

G43 H77 Z1.

M8

G98 G83 Z-1.25 R-.59 Q.1 F4.

G80

M9

G91 G28 Z0. M5

That looks correct. Is it not doing what you want?

Cathedral,so what youre telling me is all I have to do is change my G99 to a G98? I could do that manually.But then the tool is still going to retract to Z-.59 isn't it?

No, your tool will retract to the clearance plane, which is wherever the Z is at the start of the cycle. (ie G43 z???)

That is the whole point of G98

Go to your control def, under machine cycles choose return to initial height

G0 G90 X? Y?

G43 H? Z.05

G98 G81 Z-? R-.64 F?

G80

Will that not do what you want?

problem there is, if I told someone in our shop, keep bumping up the feed till something almost breaks, what they would do is just turn the feed way up and go back to whatever game they were playing on their I-phone. Then, after they snap off a $200 cutter, they'll stick in a new one, press cycle start without checking to make sure nothing moved, and scrap the rest of the order.

Ok I'll try that. As for roughing I'm using pct curve cut.75 cobalt rougher. Running 325 rpm at 5 imp. It seems to be running pretty nice now. .375 step down. .25 step over using dynamic core.

 

Then using area for the pocket.but the helix entry is killing these cutters. What angle is easy on the em?

Wow! My first attempt at inco today. .. what's the trick to drill a .5 dia hole 4 inches deep? All I can use are cobalt drills. I'm running 200 rpm 2 imp .05 peck flood coolant. I can get about 2 inches deep,just can't get the heat out,and it work hardens. .

For a cobalt drill, you speed is way too high, your feed is WAY too high, and each peck you take is like rapping the end on the drill with a ball peen hammer.

I've been having good luch with OSG VPH drills.  They are powdered metal, so they're  nowhere near the price of carbide and they work great ininconel.

What I hate is having to make a spring cut

I like to use 2d pocket toolpath, parallel spiral and Island facing to go around trees.

Don't forget the empty coffee cups...

Those are used for leaving rings all over the blueprints

around here it's like this;

Make sure the enclosure is filled with chips up to the door

The coolant tank should be low enough that the pump is sucking air

DO NOT add way oil until the machine alarms out.

Pins and gages from the previous job should be scattered across the workbench

Pins and gages for the current job should be nowhere in sight.

If your parts are on a cart, make sure they are accompanied by several empty potato chip bags and Monster energy cans

And always remember to leave dirty rags EVERYWHERE

You need to use the material that's called out. Period. We have a number of jobs that are rectangular, but the material only comes in rounds. It's good news for our chip guy.

I didn't see a way to do it exactly, but here's a thought. Have the program set variable #3030, that puts the machine in single block mode. The operator would then have to hit single block to clear it.

What kind of machine? Could be a stuck solenoid. You can manually actuate them to see. Also check your proximity switches.

OK I've found that I can't even mill a simple circle without cutter comp!

 

I am entering:

 

G00 X-5.8 Y0 (initial position)

Z-0.1 (1st depth cut)

G01 Y1. F5. (linear move to top of circle)

G90 G3 X-5.8 Y1. I0 J-1. (mill circle)

Y0 (linear move back to center)

 

I get error: "Invalid I, J, or K in G02 or G03"

 

Are you guys saying the G01 linear move needs to be on the same line as the G03?

You need a G1 on the last line, Y0

I have that problem on my laptop. Go to screen resolution, and change it to "Landscape". Then try to hit the OK button before it reverts back.

Some engineers are more flexible than others, and it's sometimes hard to guess. There may be no reason at all for a 120 deg pont, or there may be a real good reason. Can you drill them with your coolant through drills, a tad high, then go back in with a HSS drill ground to 120 deg and pick out the point?

did someone say search?

go to your post and change "brk_max_angle" to something other than 1

Sent everything to my re-seller and they verified what you found Guy, works in the old verify but not in the new simulator. They're submitting the bug to CNC.

Maybe they'll get it all to work someday. Until then, I still like the old verify.

Ok, this seems to be a bug in verify. It works fine in X5. In X7, it looks right in backplot, but it won't work in verify, UNLESS--

if you delete the inside radius and make it a sharp corner, all is well

Instead of using a custom file, try importing it and using a custom level. Delete the centerline too. I don't see anything wrong, though

Where it says "CUT" at the bottom, is that in the file? That will definitely screw you up.

Do you have undefined selected as your tool type?

Can you post a screen shot of your geometry?

What Cjep said, + if you have a center line, it has to be a center line.

I would select your chain and blank it. Then hit Fit to screen and delete everything. Then unblank your chain.
