i recently switched my hurco machines from basic nc to their isnc option. with basic nc the post allowed me to put in two peck depths while drilling long holes. normally i use a standard length drill then go back in with a long drill to reach final depth. with the isnc option it only reads the first peck depth and not the subsequent peck depth. is there a way to change this in the post?

I am having problems with my post starting pocketing operations with i's and j's on the first line [helixing into pocket] and then radius's after that. the toolpath looks fine in mastercam, but it tries to cut ouside the pocket when i send it to the machine. how do i change the first lines i's and j's to radius's? i think that would solve my problem. thanks.

many thanks to all of you. i think i finally have everything working properly. i dont even want to begin to think about where i'd be without this site. prob even less hair on top of my head then i do now

thanks, works great!!!

ok, i tried a few different things with this, i hate to sound like i know nothing about the posts, but what i do know is very little. could you be a little more specific please? thanks for the help, i will keep trying.

i am using the mpmaster post, and i would like it to post the tool lengths along with the diameter ect. is there any to do this?

"Looks for work shifts, there should be tool info in there as well. So your H will have the length but when using wear to D will be zero to start" i couldnt find a work shift. i dont know about these machines.... they have a diameter, diameter comp, and tool offsets page. the tool offsets page is where its been reading the number for height and tool comp. the other two have no effect on the diameter of the tool. to me it makes no sense, but must have to someone. i guess the best way to get around this is to change the h value. is there a way to add 100 to all tool height through the post? say tool one would be t1 h101 d1? there is a height offset with the tool info that it reads from, so i would rarely have to change it in the tool offset page. thanks to everyone for your time and input. it is very much appreciated

"but the machines graphics show me about an 18 inch radius for the lead in/out " By any chance, do you have a tool length offset stored at this value? I've no Hurco experience but it looks as if the controller at the machine is reading both the H and D values from the same location. you couldnt have been more right. it seems the machine is getting the height and cutter offsets from the same value. " i just had them all updated to the isnc option." Could be the updates require you to use a CC value thats somewhere in the upper end of the register. Tool 1, H1, D30, or something like that do you know of any other way to get around this?

i think thats one of my biggest problems, my machines are old. I am running version 2.21 on the ultimax control. I will run some fanuc posts through and see what happens. i will share what, if anything i figure out.

im having the same issues with that too. are you running hurco's with the isnc option?

I am having these problems going around the outside of a part, so the radius of the tool shouldnt really matter. I have yet to tackle a pocket. what do you mean tool comp?

i have messed around with the ijk's and radius's. i can get computer comp to work using radius's, not ijk's. when i try to use wear comp nomatter what the lead in/out is set to it tries to make a full circle around the part before starting to cut. any ideas?

im pretty sure i have this problem solved, sounds like its something in the post. i have hurco going over it, we'll see what happens. hurco's isnc option makes them able to read a fanuc based g code. they have their own version of g code, its very similar to a fnuc code except a few wrenches thrown in. Instead of r,z,q for a drill cycle its z,z,z and all distances are positive. I guess i wanted to get away from their version because the code was so long, there was no way to have sub programs and it liked to throw a lot of useless code in there. I do a lot of 3d work, and the programs wouldnt always fit in the machines. the help is much appreciated, i wish i had known about this site sooner. thank you

i have adjusted the lead in/out in the machine and in mastercam, mastercams graphics show me the right tool path, and the the code is exactly what it should read. but the machines graphics show me about an 18 inch radius for the lead in/out and thats what it is trying to run by machines i am refering to the hurco's that i run. i just had them all updated to the isnc option.

i am using wear comp control comp was even more crazy. i have a feeling its the machines more than the post.
