Ok,

So I know my tool offsets are set right because my haas tech set them during training a week or so ago. I haven't used it since. Although I just put in a 2" Diameter stock of Steel with a Rockwell hardness of 24. I want to turn this down to a Diameter of 1 1/4" with a .3" radius fillet. So I used IPS to generate the code that follws. However when I ran this code in settings graphics I get alarms. Here is the code that follows, the first alarm is generated at the G00 Z0.05, I changed this value to negative and even to Z-21.0 because I knew it wouldn't crasht here but I still get errors? What gives?

Thanks

Oh yeah I'm using a Haas TL-1

The code does not look like it has the .3 radius but other than that it should work. Did you set your work offsets?

[chucker]

Could you post the alarm you get it may help in finding your problem my 1st thought is that your problem is in your G71 and the control is reading ahead but with out the alarm thats just a guess

[JWB_Machining]

Yeah I set my offset by going into work setup. I brought my tool up to just touching the face of my part and pressed Z face measure. But I still get that Z over travel error. Any other ideas on how I can turn this down?

[gripper]

Hello,I don't know much about Haas TL-1 but try this below i know it's a 2 liner for the G71 and might not work on your machine but the rest should, you might have to change it back to a 1 liner for the G71. You need to have a home and safe index position in your program or it will index on the chuck! The G1 after the N101 line needs to have a feed rate as this will cause an alarm. Your G02 line was the wrong way see below. Hope this helps if not show drawing of what you are tring to do and we will take it from there...

Chucker, Hey thanks for the help. If I run the program without Single Block in Settings Graphics I get the following errors:

318 Z Over Travel

611 G71/G72 Type I Alarm (This has to do with the type of roughing apparently)

603 Non MOnotonous PQ Blocks in Z

I really need to get this Piece Turned down before 5 so I can impress my boss. thanks.

[JWB_Machining]

Thanks Gripper, I'll load that up right now and check it out.

[JWB_Machining]

Gripper,

No that unfortunately didn't work. It ave me the same Z over travel Error and oddly where you had it rapiding it gave a multiple codes error. Even after I added G00 in front of it and did some other things.

What I am trying to do however is take steel stock of Rockwell hardness 24 with a Diameter of 2" and work it down to 1 1/4". The piece I have is 4 " long and has been faced on both sides. I need to turn it down to 1 1/4" for a length of 2 inches and then I need a fillet beyond the two turned down length. I don't want a huge radius on fillet, it's just to reduce stress concentrations.

I was thinking of using setting of 600-800 RPM 0.015 in/rev and 600 fpm. Advice on this would also be great but I figured I'd just try n stay conservative. Thanks so much. Getting this done by the end of the day would be great.

[gripper]

Hi, Have you set your datum to the face of the job ie Z0. that might be why Z over travel.
the error 603 Non MOnotonous PQ Blocks in Z might be because the way you had it writen it could not reslove the arc. What you move in Z you move twice the amount in a 90 Degree move on the X

[alain aleman]

Check if the X and Z sensor is clean, restart the machine, that´s solved my problem. Try set up in the offset screen Z-30.000 (if you work in inches) for T0101 and run it.

Regarding your Z overtravel are you sure your offset went into the correct tool number? The TLs have what I think is a glitch, the cursor will not always go to the correct tool on the Offsets page; you must push reset or move it yourself.

I think your non-monotonous comes from here where you move to Z-2.13 then try to move back to Z-2.3

G01 X1.25 Z-2.312
G02 X1.226 Z-2.3 R-0.012

If it is not too late to impress the man put up a drawing (pdf file please) of what you want it to look like and I could do a sample program.

Incidentally lose IPS, I think it is not worth learning if you want to eventually become fully proficient on the machine. I have my own template programs in which I just change coordinates. Turning something down with an end radius and a fillet radius is about a minutes work entering the new coordinate values and Z offset then push the Green Button.

[JWB_Machining]

Hey, I attached a drawing, i had to make it paint so it's not to scale or anything, don't ask. I just need the code for the part that is turned down to 1 1/4. And the Chamfer at the top isn't really important but it'd be nice.

[Geof]

Bit maps I can handle.

The following code does not use Tool Compensation so I have included the tool nose radius using 0.015 which makes the radius 0.315, the Z at the start of the radius less negative and the X at the finish of the radius larger. I also put chamfers at both sharp corners and these are more or less freehand.

Make the start position ahead of the G71 Z0.1 as I suggested previously.


G00 X2.08 Z0.1
G71 N101 Q106 etc
N101 G00 X1.20 Z0.005
N102 G01 X1.25 Z-0.145 F0.005
N103 Z-1.885
N104 G02 R0.315 X1.88 Z-2.20
N105 G01 X1.95
N106 X2.005 Z-2.205

That should run.
