Well, I discovered that my top of stock rapid planes were fine, but I was not using the clearance plane option at the top of paramater page. I check marked it and put a small clearance in and posted and got a G1 in the proper place..... I usually do have the clearance plane checked and never noticed this issue. Also the rapid is forced in the post at ptlchg "G0 ...." So you probaly hit the modal problem right on the nose. I will keep looking. Thanks [ 03-05-2003, 12:31 PM: Message edited by: Andy ]

I will check that out, I thought I already did. Thanks

I would suggest a redwood post. Less bugs!

Well, thank them for the 1018, save you a lot of heart aches!

Nominal, I think your correct. This particualar combination just happen to show up at the machine. First time.... For temporary, I forced the sgcode and it outputs on every line and that will work until I can fix the post. Thank You, Andy

This has always worked perfectly, and then today suddenly: Normally I get a G0 for lead in then a G1 on the first feed move (linear in this case and Contour). Today I get no G1 and it rapids for the feed cut. My post has sgcode on that line but it appears not to check the modality when it gets there. This does not happen if I post just that OP, but only when it follows another op with a different tool. I suspect the interpreter program is not working properly. What is the name of that program? I would like to replace it with a backup and try again. Andy

Tony 1.414 is the secant or cosecant of 45deg. I think your formula gives the distance from the radius to the 90deg corner formed by 2 intersecting lines tangent to the arc and whose intersection is 90deg. OR, more graphically, take a square hole, insert a round shaft (tight) and the air space left in the corner is that distance (measured along a line through the center and to one corner of the square. Close? [ 02-27-2003, 06:22 PM: Message edited by: Andy ]

Thanks for the suggestion Plast, however, I have Windows ME, and one can View as a thumbnail (Not the MC file though),and there is no Quick View on the Windows ME Disk. ????

I tried all above suggestions in the previous thread and it wont work in explorer. Windows ME and MC 8.11 When I right click there is no choice for Quick View????? Any suggestions? -------------------- Gordon Engineering Eureka, Ca. V8 Lathe and Mill [ 02-24-2003, 11:30 PM: Message edited by: Andy ]

Hey PhilCott, How does your machine know when you are out of stock?

I have a Mori SL15 and we do occasionally bar pull. I actually make my own grabbers to pull the bar. I use a piece of round, bore the end to the stock size for an inch or so. Then split the puller as far as necessary and it collapses slightly. Works great. I rewrote my post to allow me to input in misc integers and variables. So, in the cutoff op say tool#5 the misc variables will call up the next tool, say tool #6 (Bar puller), and after the cutoff is done it goes to the puller and does the rest. Integers: MI9 Stock pull yes=1 MI10 Tool # Reals: MR8 Stock to Grab Z- MR10 Pull Distance Z Incremental (W). The post then looks at these entries and outputs the grab, chuck relase, pull, chuck tighten, and pull off. Works flawlessly everytime. Unless Data entry (Me) screws up.

1965-1967 Viet Nam. There was a lot of protesting then against the war and the protesting was not against the soldiers. In that case the protesters were correct. Bad war. However, this is not the same as then. We must be very sure this time that we know it is the correct thing to do.

I think it means press the enter key? Andy

Jack, As far as a special forum for geizers, forget aboutit, bad idea. I was visiting in Prince Rupert in 1976. We were looking down at the train tracks next to the inland warterway and all were expecting Trudeau to get off the arriving train that day and he did. As I recall there was no fanfare. I barely knew who he was. I guess I was a typical american dum tourist! Andy

Bummer, I am #3 1944. Andy

Does one get a special award when the number of posts=member number????

Biggest mill part we do is 8x16x4. Smallest maybe 1/8x1/16x1/4. Lathe, 8"Dx10 long. and smallest, .06D x .375 L By far the hardest job is small holes .022"D

I have a job in now that is Hastaloy X and it apparently has 50% cobalt, and Nickel, Chrome, etc. Sounds nasty. I have machined Monel before but this stuff is probably worse. I need to Tap a 1/8 pipe thread 4 places. Good luck to me!!! Andy

We use liners, (Steel tubing with collars) that bolt in at the rear of the spindle tube and the collars OD and Oring fit nicely in the spindle tube and the tubing holes are about .020 bigger than the stock being used. Also, as Trevor said, just make collars if your stock isnt too long. We have made the collars out of delrin but wood is fine. Andy

Hey Jack, GREAT picture of the classic JACK

Ditto, Toolfab, That is about what I use to Drill .039 holes in A2. We make small hole punchers for the jewelry industry. However, we peck only .010 each peck. And change drills often. Drills are cheap, removing broken drills is expensive. I actually check the tips in a microscope (New drills and used) occasionally new drills are junk.

You think any pirates would bid on this? I dont know how to make this a link, but: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...&category=25281 Andy Iguess I did know how to make this a link! [ 01-26-2003, 05:15 PM: Message edited by: Andy ]

James, Interesting you should mention piston turning machines (lathe?). I happen to have a 1945 piston grinding machine. Probably built to grind cast iron piston. We converted the machine to grind swage dies for a customer, which are 6" long shafts about .75 dia. in a cam like shape. I converted this mechanically operated machine to run off a 286 pc. (So we didn't have to be there to crank knobs and reverse feeds etc.) It actually works great for an old piece of junk. There is a slide for the x axis, which we put a stepper motor on, same for Z. However, the cam shape is still made by following a 6"dia cam template with a follower roll. So, because of this cam, it does not qualify for the discussion above, but I thought it would be interesing to mention. Andy

Are you trying to cut a section of an ellipse in the lathe? If so, then yes, you can cut an ellipse. The section of the ellipse you are cutting will be short line segments, or tangent arcs, or a combination of both depending how you program it with MC. Andy
