G-Code, CAD, and CAM discussions / Re: Double taper

« on: May 17, 2008, 03:35:26 PM »

To create a taper the X & Z must be commanded on the same line :-

e.g.

G00 X5. Z1. G97 S1000 M3
G01 Z0 F.1
X15. Z-5. (produce a taper @ 45 degrees)
X5. Z-10. (and back down the other size)
X20.
G00X50. Z50.
M30

It's not that simple, G41 and G42 will offset to the left or the right of a line but you need to program lead in/out lines to.  It is normally easier to reprogram the code with a .005 smaller cutter than you are actually using.

Hi M.Jonas,

the code you have written will produce 3 100mm squares at 3 different points, the points are set in the work offset table.

If the squares are in the wrong places then the work offsets are set wrong.

More information will help to solve your problem.

Hi Hood,

your points are duly noted.

I would agree with you if the Boxford had the sort of power you are playing with.  A 10x1.5 thread on the Boxford can get out of pitch if the spindle stalls at all when the tool starts to cut.  By having more slots the pitch is corrected much sooner and the thread saved.

Nothing wrong with that screen, if it suits your way of working its got to be good.

Hi Simon,

if you go to diags is the current pulley set to 1?

I have a disc with 7 10mm slots and one 20mm slot, Mach reads this with the timed signal through a CNC4PC C3 board, I have very good control from 200-4500 rpm with no spindle calibration.

I also found that if the slotted disk was painted black it was better, ? , answers on a post card 

You will find if you do threading you will need a multi slot disk,  more slots makes for better pitch control.
