    HOW TO USE CALL OO88?

    No only 3+2

    HOW TO USE CALL OO88?

    I have a postability post and it is only posting at header. Not for every rotation. I need to figure that one out.

    HOW TO USE CALL OO88?

    I want to use CALL OO88 on a MU 4000 and MU 6300 okuma. Do you post out CALL OO88 with every rotation move? Or just at the start of the program and the control keeps up with the zero from there on. Also, do I need to cancel? Thanks, Steve Austin

    Anyone dynamic milling 13-8 PH?

    On aluminum I zigzag but not hard metals.

    Anyone dynamic milling 13-8 PH?

    Here is a vid at 1000sfm dry. Material here is 17-4 at 44rc. 13-8 is a little tougher but hardest is equal to my material.. this tool could have busted after just one part. https://youtu.be/BsBDnO9yMaQ

    Anyone dynamic milling 13-8 PH?

    13-8 PH 42-48RC. I program at an aerospace shop and we have many older poorly programed parts I am modernizing. I have been roughing with 1/2 to 3/4 solid 5,7,9 flute at 300sfm 5% radial and .0016 for 1/2 and .0024 for 3/4, which give about 50-60 IPM. I am asking because I have seen some examples of SFM from 400 to 600. The IMCO book which is the brand we use says 440. Niagara show more and cutting dry. Has anyone had any luck cutting dry? What is your go to numbers? Much appreciated Steve Austin
  7. I am about to test several solid and insert Feed Mills for roughing 3D pockets in TI 6AL-4V and 13-8 PH Stainless 42-48RC. Any suggestion for toolpaths? These are running on 3x and 4x Okuma osp200 and osp300. I have thru coolant. I have never programed for a Feed Mill. Much appreciated as always, Steve Austin
  8. That works great, Thanks Husker! I took the 5x post class with Colin but is has been a couple years now and forgot about that switch.
  9. During the day I discovered the plane trick with C0. A5. and that worked I will try the others now. Thanks, steve
  10. This is after a tool change. 1st tool cuts at A30. C10. Next tool cuts at A0. C10. In this case the spindle is square with the table but it looks crazy. Thanks for responding, Steve
  11. Using the generic 5x post AC head head I cannot get c to zero after it has rotated. If is is cutting at A90 C5. When the next toolpath should be A0 C0 only A goes to zero. It is unnerving if you are not used to it. Is there a switch for this? Thanks, Steve

    generic 5x post giving crazy A numbers

    So I figured it out. I had my limits set in the machine def but not in the post. I had forgot that this post does not look at machine def for most settings. Thanks for looking. Steve Austin
  13. I created a post from the Generic and thought I had it correct. When posting individual tool paths the numbers are right but when posting together (null tool change) the numbers are not correct. This is an AC SNK horizontal For example by itself I get C180. A-4.921 when null I get C-89.135 A5008.907 Has anyone seen this? my parameters are: #Primary axis angle description (in machine base terms) #With nutating (mtype 3-5) the nutating axis must be the XY plane rotaxis1$ = vecy #Zero rotdir1$ = -vecx #Direction #Secondary axis angle description (in machine base terms) #With nutating (mtype 3-5) the nutating axis and this plane normal #are aligned to calculate the secondary angle rotaxis2$ = vecz #Zero rotdir2$ = vecx #Direction thanks Steve Austin

    ROUGHING STRATEGY FOR LARGE AEROSPACE AL PARTS

    We have a Mits AXD 2.0" that I use when I can but on this part the pockets are too small. So I will go for the more traditional milling on this one. I will try a ZIG ZAG path to get up to speed on as much as possible. Thanks, Steve
  15. I have been programming for an aerospace job shop for several years. Up until now I have only work on small to medium sized 3, 4, and 5x mills. On these I mostly rough with dynamic paths. I am now working on a panel that will run on a large SNK HEAD/HEAD horizontal profiler with travels of 48" x 120" cat 50 20,000rpm Fanuc 31i. So my question is: considering the size and acceleration of a large machine, what type of roughing should I be focused on: modern dynamic roughing or old style roughing .5D axial and .5D radial step over? On the smaller machines the dynamic is generally faster and more reliable. I am not sure if this is true for larger machines. Do any of you have experience with larger profilers like this? Do you have any other advice that would be helpful here? Thanks, Steve Austin
