How are you planning to program?
ez-guide? or g-code? CAM?
Mill a hexagon on lynx 220lm from round bar is this possible ?

G code or I've got mastercam 9

Hi,
This is a G-code for a 50mm Hexagon with an axial-live tool, Fanuc 18T.
Maybe you need other M- or G-codes.
Look also at the Doosan attachment for c-axis milling and side drilling/tapping.
When you use Mastercam 9 you need a proper post-processor.

Thanks ill give it a go my control is fanuc oi- tc so might have to change some codes much appreciated

Does that program do it in 1 cut what about a really heavy hex, can you rough it in a canned cycle ? Regards Matt

Hi Matt,
This was a try-out on a Delrin (PCV/Plastic) round bar with a 10mm mill, one cut.
You can program multiple passes or start with a large offset, maybe Mastercam can help with the g-code.

Heavy_Metal.
Than you

Thank you the 50 mm hex program worked a treet but I've just done a 35mm a/f and the flats look slanted could you show me a program to see what I'm doing wrong sorry to be a pain thanks matt

Hi Matt,
The next code should work.
When you stop between line N1 and N2 you have to execute, in MDI-mode, the code G40 G113 (G13.1).
It is not possible to make the sides 100% flat, than you have to mill with an Y-axis or a VMC-centre.
Maybe you have to reduce the Feed-rate for a better result.

I wonder if a 1/2 solid carbide end mill will be better as I'm only using a standard and sticking out 41mm what's the best cutter for this type of machining is it a ripper?

Hi Matt,
Solid carbide is always better (for steel) than HSS/Co but needs stability and no vibrations.
You can use a rough/ripper mill when the smoothness of the surface is not so important.
I don't know what the material is for your job.
There are a few things that matters:
* cutting depth (radial)
* Z-depht (axial)
* lenght of the tool
* Feed and Speed
* stability toolholder and tool
* power live-tools
Regards,
Heavy_Metal.
Thanks I think I'll go with the solid carbide but the maximum cutter I can use is 1/2 inch as that's the biggest collet I have regards matt

I'm currently not seeing the results I'd like with the G12.1. Attached is the current code (Citizen L20-Mitsubishi control) and the blueprint. The print is in inches but the program is in metric. I programmed the final part dimension + the radius of the tool (.125"), this way the R value on the offset screen is 0.
The issues are as follows, the final dimension is approximately .032" to big on the .072" +0./-.004" dimension(width across flats). I've programmed the X and C axis radially. I verified that the tool is centered (X0./Y0.) to the sub-spindle.
Also, there's no .127mm(.005") radius on the corners of the square.
As the program reflects I'm using G41 and G2's. Per the attached picture captured from the Instruction Manual for the Citizen L20, I should be using G42 and G3's, which is correct? I'm wondering if this is why my part has no .127mm(.005") radius on the corners of the square?
Thanks in advance for the support.
I know this is probably a late answer but I am sure you will find this of use, very basic but I use it on my Lynx 220 and it works fine. you might have to play around with the speed/feeds for your material but hey ho

Correct. G12.1 is used with G13.1 to cancel. If you'd like the classroom manual on this, please email me.
