5-axis curve toolpath w/ 4 axis output

[RMagnusson]

Hello,

 

The file I'm working on is on the FTP in the MCX2 folder named "4th axis engraving".

 

I am trying to engrave something on a surface thats bent near the center 45 degrees with a .5" dia 45deg sweep radius. I would like the tool to stay normal to the part surface as it cuts, but my posted code looks like absolute crap. Tons of Z moves where there shouldn't be, and the 4th axis just keeps spinning in the same direction. The feed is all over the place also.

 

I am running a horizontal mill with a simultaneous 4th axis, but I think my post might be lacking. Maybe machine def.

 

Could someone take a look and let me know if my toolpath is junk or my problem is elsewhere?

 

Thanks

You have mail. It has to do with your WCS and the T,C planes. I would like to email you mine, but I don't know how to send it to you.

Lol, that sounded like, "n00b mistake" as I read it I'll check my mail, thanks.

My mistake

It looks like you had it right.. When I posted it, it looked to be OK, feeds were deg per min ext. few Bs' all range closely back and forth, hardly any Zs' like you would expect. Check your MD maybe?

 

You have mail.

Woohoo! Not such a noob after all : )

 

I'll take another look at my MD, CD and post. Gotta be in there somewhere....

 

Thanks again for all the help. I really appreciate it.
