Angle drilling lathe

[ProToZyKo]

Hi

Im wondering if there's any G code to turn the coordinate system a specific degree to make it go in Z and X to drill a hole with a angle head.

Sure i could calculate the coordinates but would be much easier if such a G code exists Also easier to check if the angle head is set right to be able to use HM drills.

Example G00 Z5. X100.
G## 30 degrees
G81 X80
It would drill to X80. and Z# in 30 degrees.

Fanuc 18iTB

what kind of machine are you doing this on? Also have you checked the FANUC operators manual? If you have one.

G68 (G68.1 on some sytems) Coordinate Rotation. What machine make & model are you using?

Thank's for reply

Machine Omega OM-80
Im not in the machine atm, i wasn't sure this was even possible so i haven't checked the manual since it's kinda hard to read
Can't really stop it for too much testing, how would the line go?

First of all, be aware that G68.1 is an option, and it may not be turned on in your control.

The attached .jpg shows the command format.

Looks like this is something i don't have

What would you guys prefer? Calculating the coordinates by hand/edgecam, upgrade to get that option, upgrade to Manual Guide I.
If something should go wrong we can't really take the drill out in manual mode without this option :s

We are considering Manual Guide I, kinda hard to get any info on how good it is, im used to FAPT and Okuma's IGF, and if manual guide i is as easy and good as that i can't see any reason not to buy it.
We mostly program simple part, big machine and only 3 axis so not that advance.
I would think that Edgecam would be slower to program our part's and changing cut depth, feed rates and speed.
Anyone with any experience?

Hi,

Optionally the Fanuc lathe controls can use an angle command. Either the X or the Z command can be replaced by an A command.

Instead of:
G0 X50. Z2.
G1 X13.05 Z-30.

You can program:
G0 X50. Z2.
G1 A210. Z-30.

Or:
G0 X50. Z2.
G1 X13.05 A210.

A+ is Counterclockwise from the 3 O'clock position. A- is Clockwise from the 3 O'clock position. A0 is or Z+ direction. A90. or A-270. is the X+ direction. A180. or A-180. is the Z- direction. A270. or A-90. is the X- direction. The A command can be programmed to the 3rd decimal place (A12.345).

I hope this helps.

Is it a combination of zero shift and rotation?

Yes, it is.

G0 X50. Z2.
G1 X13.05 A210.
Would only make it go in X direction.

What's the best option? Upgrading to Manual Guide I and G68.1 or use edgecam?
We have allot of different part's and we need to best way to program.
