Apt

[nabil_elbadri]

i need to learn about high language programming (APT), so please if any one could tell me if there is any web site that i can download some refrences from it for free
thanks:

Uh!

Let me look into my old dusty files.

I was learning it about 10 years ago.

See you later:

:-( my old PC just died from natural causes...

I had a bunch of pretty stuff in an old 80286 PC, including my first Qbasic programs and APT compilers. But I couldn't make it run this time.

I don't know how much have you investigated so far about APT, but here is what I can say:

APT is acronymous for "Automatically Programmed Tool" or something like.
Basically if you take your CAM software and remove its graphical direct manipulation, what is left is APT.

In G code programming you are working directly with the tool path. Instead in APT you are working with geometrical entities, then defining the tool paths between them.

For example you can program something like this: (not exact syntax but give you the idea)

P1=POINT (0,0)
P2=POINT (10,0)
P3=POINT(10,10)
L1=LINE(P1,P2)
L2=LINE(P2,P3)
L3=LINE(P1,P3)
C1=CIRCLE (TAN L1, TAN L2, 3)

What you defined here was basically a triangle with vortex at (0,0), (10,0), (10,10) and a circle with radius 3 touching two inner sides of that triangle.
You haven't done any tool movement yet. It is the same in the graphical software: First you draw geometrical entities, then you make some vectorial "characteriscs" over them, and finally you create the toolpaths wich follow that characteristics.

There is some info in the machinery's handbook also.

I attached one old APT compiler. I hope it can help you.

Here is some jargon:
