Im working on getting the new to me LNC8 up and running and am trying to learn and tackle the control and the use of the LAP programing while I wait for things to come in (tool blocks, holders, etc..). Its quite different than what I am used to (OSP3000) and Im ending up with some questions that Im hoping someone here could enlighten me on...
I threw together what I think is correct from the book example, and pasted it below. (used an old program from the 3000 as the starting point) The questions I have are...
1.) I like to use line numbers - in using a line number in the same line as the "name" of the contour - N307 SHP01 G81 - the book does not show a line number on that line, despite line numbers after it. So Im trying to determine if I should not use a line number on that line, or just use the line number as the name and call that in the G85 line? I see some examples in the book where they call the roughing with the "name" but call the finishing with a line number. And of course no explanation why. Or - maybe I should treat it a bit like a sub-routine? And through that (the contour defining portion) up at the top of the program prior to the main program - where not having a line number would be less drama for me? Many times Ill have two or more LAP cycles in one program and could see having both line numbers and names being helpful - as I long hand all of my programs - no CAM.
2.) I wrote the program as the book showed (omitting the use of G84) including tool change location. I generally do not use a different tool for roughing and finish... and I usually use the same tool prior to the LAP cycle, so its already called up. So to avoid the wasted movements both prior to starting the roughing, as well as for the finish pass, would I just omit the tool change lines (Xt,Zt if youre thinking in terms of how the book lists it)?
3.) Does it look like I did it right? Or should I look at formatting things differently. The reason I ask that, is that there are some programs that were in the machine when I got it, that used LAP, but only roughing, they never called a finish pass, but they are formatted completely different than the book/my attempt (called the G85 first, THEN specified the contour with the G81). And that made me think maybe there is a different/better way to do it?
4.) If I am completely off base with what I have below, Id love to see any working examples anyone might be willing to share.
Thanks
