Reaming out holes

Sorry this is probaly a very basic question but I am stuck.
I am using a 6mm bit to drill two holes at 15mm centres, then ream them out slightly to 6.8mm. The first hole is fine, but as soon as it hits line 12, it travels back to the first hole to do the reaming. How do I hold the coordinates (line10) for the 2nd hole reaming action?
Any help greatly appreciated.

1. (Hole # 1)
2. G00 Z0 F60
3. G00 X0 Y0 F60
4. G01 Z-5 F60
5. G00 X.4 (ream out to 6.8)
6. G03 I0 J0 F100
7. G00 X0 Y0 Z0 (back out of hole)
8. (Hole # 2)
9. G00 Z0 F60
10.G00 X15 Y0 F60
11.G01 Z-5 F100
12. G00 X.4 (ream out to 6.8)
13. G03 I0 J0 F100
14. G00 Z0 F60
15. G00 X0 Y0 F100

your line 5 and 12 are the same. It is X location. Since you drilled the next hole on X=15, the next reaming should start X=15 as well.

That's one crazy program, this is all you need, even this is not a normal program, I have just followed the same format as you have posted, which is far from the norm.

( Ream 2 Holes )
G00Z0.
G90G00X0.Y0.
G00Z3.

Thanks guys for taking the time to look at this, but I read the manual again and found gold. Add G12 at the bottom of each hole and it works perfect!

What kind of control are you using, as that is a strange G-Code format?

...Reaming was the wrong term used. Its called Circular Milling that you're using
https://www.haascnc.com/service/code...value=G13.html

It's also a good idea when programming to be organized and follow a set Format for each Tool..and not do it mickey mouse. Read your programming manual 3-4 times helps in the long run if, new to CNC stuff.

Good Luck on your mission.

That is your cam software, what is your machine control.

You dont need G03 at the bottom or a hole and g00 x0.4 should be g04 for a dwell not a position move !!
