I was scratching my head at the bit where it looked like the tool was scribing INSIDE the cylinders at a very weird angle- tilting in X, Y and Z and god knows what other axes lol... 'till I figured it out:

Apparently high compression engines, like dragsters etc have to have a releif helical slot machined on the internal face of the piston cylinder- otherwise the compression is too high and things erm.. break and fall apart (or so my mate says after watching something on the telly about US drag racing).

Dunno if this is true, it doesn't sound right cos surely they'd have to put a sleeve inside the cylinder for the piston to mate with- it couldn't just go straight to aly could it? but it's the only reason I can see for the weird movement the machine is doing when it looks like it's chamfering the cylinders... any ideas anyone?

And as to the G-Code.. I beleive even Prof Hawkins would have more that a little difficulty debugging it lol.

[edit] have bitten the bullet and E-Mailed the company to ask them what the machine is doing when it's making those weird multi axeis movements- I'll look like a noob but sod it, curiosity got the beter of me hehe.[/edit]
