need help,nothing seems to be right

[jabran200]

I am a student and i am trying to write a gcode for a file i thought i had it on the right path but it turns out when i try to simulate my program it alwasy comes out wrong.

Can someone please have a look at mines its just 19 lines so that i could check if i was on the right track but the teacher showed us how to check on alphacam and i cannot find a copy to download of that and it never works with free ones.

Weird thing is that the programs the teacehr gave us come wrong on the free simulators as well.

Ihave attched bothe the nc program and cad drawing.

Thought you guys might need this info but i don't know you guys are pros lol . We used an emco155 and fanuc21 codes.

Just tell me where i am going wrong and that would be perfect.

No arc center, on the G2/G3 (need I & J).

Maybe this link will help you.

I cannot open it, says not a valid file... I tried

Russell.

@swithcer
Would that be the i and the j?

@russel
open the nc program in notepad and cad file in autocad.

thanks for that switcher, you answered my question. Is that all that seems to be wrong?

Anyone know where i can get a copy of alphacam for learning use?

The rest looks ok, I'm not sure about alphacam.

If you want a great sim, try NcPlot (Free Trial) www.ncplot.com , get the latest beta, works GREAT!

Thankyou i understand where i went wrong now. You saved me from mutilating my workpiece lol.

Thanks for the NCplot link as well works well, quite similar to alphacam actually.

I think you'll need 2007 though.

[jabran200]

Yeh most likely since i used a 2007 at college. Thanks anyway guys I REALLY appreciate it since i have the outline done now, i'll attach the file so you guys can have a look as well incase i made a mistake or soemthing but it did come out fine in NCplot (thanks again switcher)

You might want to look over your Feed/Rapid, looks like no "F" value at start of program.

Is the one at line N90 not o.k? as machining does not start until the next line.


Thank you
