Lathe Macros

My lathe uses Touchy. As I do almost everything with the macros I don't really miss the preview.

I really like the preview. Old school, preview and simulate when you can and it's reasonable. Heck, define a big Z tool offset and simulate phisically!! I have seen to many hard crashes by a missplaced character when coding some very simple program directly on the CNC. Simulatinons are cheap, repairs and redoing entire parts are expensive.

(And sorry for my poor english. You should have noticed by now it is not my native language)

Hi Andy,
I see that the threading page only has inputs for pitch and OD. Does this mean that it does all the calculations for metric and unified threads automatically? I just cut a test M5x0.8STI (the Helicoil tap for M5), which has these dimensions:
 

Setting 6.145mm OD in your macro, it first did a turning pass at about 6.05mm, before turning the thread. Does that mean you are expecting the nominal diameter to be given, and are turning off the H/8 thread tip on that pass?
 

Since the Heilcoil manual gives a dimension for the taps major diameter, rather than a nominal diameter, do you think I should be inputting 6.145 + (6.145-6.05) = 6.24mm into the lathe macro as my nominal diameter, so that macro can remove the H/8 again?

Cheers, Mark

Yes. It's a bit out for Whitworth or BA because of that.
Note that the number entry box will let you type (for example) 11 then tpi-pitch then in-mm to program an 11tpi thread.

Yes, exactly that.

Thanks for the quick confirmation Andy. Nice work there. Another good reason to avoid Whitworth, BA etc

Okay, for 0.8mm pitch, I'll need to add 2x H/8 to the Dmaj, to get the nominal which your macro starts with. So my DMaj of 6.145mm will be Nominal of 6.284mm given a tool with no radius.

hello,

thanks a lot for your job. It will make our life better and easier with this macro page. It is really nice stuff!

I want to aske, if there missing drilling and grooving page in V2 macros which I downloaded from AndysGit , is possible to implement to V2 running on v2.8 or move to v2.9?
