    you might try inserting an "EOB" on that line to see if it moves the "/" to the next line. if it is saying that the prg. is protected then look at parameter # 3202 bits "NE8" and "NE9" and switching those from on to off this might let you delete it. HTH Ken

    as far as i know you have to do them separately. one thru the program page , the other thru the offset page. sending the offsets should create a simple program that you can reload and run to reload the offsets. would be nice if there is a way to do it. but then you would have "G10" data in the program that would require editing if any changes are made during the run.

    i have never had good luck getting a scallop, or flow line path to filter into arcs. to smooth it out you need to really bring down the filter tol. draw back is it genrates alot of code. depending on the shape i've had better luck using surface contour or the 2d wire frame paths. paralle paths filter really nice if your shape allows it.

    +1^ on the mit. "apx" cutters. we are using the "apx3000" .625 to 1.5 dia's on every thing from alum to ti 6al-4v. so far we have good insert life. also using the "ajx" cutters in ti 6al-4v with outstanding results doing some serious roughing for us. HTH Ken

    the "tec-ease" web site also has a very good "gd&t-tips" section that gives a pretty good explination in real world terms as to what the each symbol means and how to inspect it. HTH Ken

    not sure what your tool path looks like, but if you look at your posted code " N130 X1.325" and your screen shot shows "X-1.325" per "tozmasters" post maybe try switching sides in the roughing pattern. also "N590 G1 Z-.0079" is this correct if not it might be how the rad. is defined on your tool, compted to the center not the edges. most od paths in mc are usually programed on the X+ sidein mc. not as you would always see them in relation to how the machine is orintated.

    [Maybe I am mistaken for a Haas lathe, but shouldn't the rough direction be on the other side of the part?] after taking closer look at your settings i also noticed that you have the comp direction to the left. not sure but i think that should be to the right. that might giving you the "u-.02". Ken
  8. kh012
    not an expert on haas lathes but looking at your screen shot you have the comp set to wear. when ever i use the canned cycles i turn the comp to off. that way the numbers match the print. then i do a seperate finish pass with the comp on set to control. it maybe doing that because your tool might have comp to the center of the radius not the z/x edges.

    we have mitutoyo crysta apex 574 cmm full cnc with probe rack, ph10t head, tp200 module. this is in a climate controled room at 68 deg. we use the mcosmos software. i found it very easy to use. just like setting up and programing a mill just go step by step. it will load all types of models but prefers "sat" models. no surface normals to deal with. one thing i found is that it can be too accurate, getting into pi##ing matches with the operators. HTH Ken

    the method i described was shown to me by the instuctor when i took the classes for V7. when we went to V8 we upgraded to mill level 3 so it eliminated having to do this, never tried a net surface. but after the upgrade didn't need to do it, so never looked back. Ken
  11. kh012
    back in the day i had to do this alot. you have to create curves thru the surfaces using the slice feature. then you have to pick all those splines to create one surface. pay attention to the ends of the splines because sometimes the surface will roll under. if it does tweak the end points of the splines and try again HTH good luck Ken

    we are also looking for a vertical. just talked to the matsura salesman. the "VX" series might also fit your needs, comes with a fanuc 31i controler. he claimed it was on par with the mori nvx series, but you know how that goes. Ken

    just to add another machine to the mix. we are also looking at kitamura , makino, okuma. the kitamura actually spec's out a little better then the dv5100. if the majority of the work is alum might be worth a look. HTH Ken
  14. kh012
    on the controls 3 of our mills and all the lathes have mit. controls. the dv5100 has a MSX-504IV control it is in reallity a fanuc o-imd control. every thing spec's out the same. we run fanuc formats on all our programs. all the drive hardware is fanuc on all the machines. with the AICC this machine shreds in alum. we rough and high speed finish ti-al-4v about 120 hrs a week with no problems for over a year. holds tol. in the tenth's all day long. HTH Ken

    we have a DV5100 with a ddrt260 head, a dc5 , sv500 ,and a mv55. we have found these to be really thight and accurate machines. we are currantly looking to add another dv5100 / ddrt260 machine to the shop. we also have 3 mori lathes also no problems. the only draw back is sometimes the service from ellison can be lagging.

    i think you need to change the "NC" file name to read the new prg. #. without changing the nc file name its still calling the original nci file that has the old prg# in it. HTH Ken
  17. kh012
    yes you will need to measure a cylinder to define the axis of the hole. as stated above the max. mat'l cond. is your friend to get more tol. how ever much the hole is from the max. mat'l size you add that differance to the dia .038 to get more pos. tol. never used the mastergage but the software should calculate all these factors added note: you will want to measure the cylinders in the same direction ie: bottom to top. this will make the c/l axis directions all go the same way. ++11 on the tec-ease site i use it all the time HTH Ken
  18. kh012
    your third axis or 'z' is basicly a perpendicular call out. with the referance hole perficly level then the c/l axis of the other holes must be inside of the dia .038 call out thru the hole. without a cmm a quick way is to find the x/y locations at the top of all the holes then repeat at the bottom of the holes all the locations must fall into .038 callout. HTH Ken
  19. kh012
    the problem was probably that the edges of the holes were splines not arcs , curved surface. the easist solution is to download the free "verisurf" addon from this site. it will allow you to define a hole axis and creat arcs and points on that axis. then you can use them to drive your tools HTH Ken,

    we tap 0-80 to 10-32 all the time in anything from alm to ti 6al-4v. with the small taps i never go over 250 rpm and it usually runs pretty good. for tap life look to coated taps. and if you can try and open up the hole size. with a form tap this can be a pain but doable i have some times reamed the hole to open it up a bit. i think emuge has some new taps and coatings you might want to look at.

    you said your tool offset was around .995 and your work shift was 1.5 added up = around 2.5. the absolute page will read the posisition #'s as they come from the program. the relative page #'s don't refleck this because it doesn't take into count the offsets or work shift one way to make them match is actvate the offset in mdi "T0101" look at the position page and preset the relative to match the absolute. i usually ignor the reative #'s unless i'm using them to bore a collet etc. Ken
  22. kh012
    the varibles are something i added so that you only have to enter it once at the start of the program. not at every tool. Ken
  23. kh012
    ^^^^ this is how we do most of are lathes. but we have quest851 msy. that uses a work shift for both spindles. i have the post put in G10 P0 Z[#501] for the main spindle and G10 P0 Z[#502+#500] on the sub. i do this for each tool. then at the start of the program it puts in #501=Z? #502=Z? i fill in those Z values when i find the work shifts it loads those values into the variable page then calls it up as needed. #500 is used to do a globle offset on the sub if needed for thermal expansion etc. Ken
  24. kh012
    ok with the way you are touching off then you need the work shift. looking at your pre. post you put in a value of z-1.5. this should have put the stop at z0 on the part or 1.5 from the face of the spindle if the offset was active when you ran it. take a look at the prg to see that it did indeed go to z0 stop then open the collet, feed the bar then close the collet. before going home. if it does't do this in the prg. then the tool path in mastercam is wrong. and you are getting a different z value friom somewhere. Ken
  25. kh012
    when you quailfied your tools are you using a probe or presetter or are manually finding z0 on the part, because with the probe your offsets will usually be from the turret face or c/l of the turret and be small #'s. if your qualifing from say the home pos. then you offsets will usually be large #'s. if you are qualifing each tool from the home pos. then you don't need to use a work shift because your offsets are basicly your work shift for each tool. using a probe everthing is qualfied to the turret then you use the work shift to locate the z0 in the machine.
