The back up (copy table ect.) is on the same page as the set/offsets just back up all
and type in bla bla .bck and it will save so as you can pull it up and restore at a later time it will remeber everthing tool ids numbers location set ups offset even dia comps.
John, was in meeting last week and didn't get a lot of time to play. I still can't get the tool #'s to re-sequence? Also can't seem to back up YET? and still can't get the different fixture offsets, which I'm going to need soon?
Also, if you could, can you please give me a "RIGID TAPPING CYCLE" for:
- 1/4-20 tap
- 3/8-16 tap
- 1/2-13 tap.
If you can help me with these "common" sizes, I can figure the others from there.
Have some time this week and will be "playing" with these things today.
Ok what I like to run is a simple tap cycle like this
G95 G84.1 X0Y0Z-1 R0. F(1/20) J3
THIS WOULD GIVE THE TAP CYCLE FOR A 20 PITCH WHAT EVER SIZE TAP AS LONG AS THE MACHINE HAS ENOUGH TORQUE TO PULL IT AND RPM WAS RIGHT FOR THE SURFACE FOOTAGE. THE FEED SPEED GETS ENTERED AS A FRACTION THIS IS THE BEST WAY I HAVE FOUND. THE "J" IS THE EXIT MULTIPLIER FOR THE EXIT SPEED AND FEED. IN THE EXAMPLE THE TAP EXITS 3* FASTER THAN IT ENTERED AT.
These are real nice features of the machines It blows my mind on how exact it can locate the C and Z axis.
On the other size taps the rmp would change and the feed would follow the lead of the tap in a fraction form F(1/16), F(1/13), and so on.
I will try some time this week to take som pics of the setup screens Becuse I know a picture is worth a few thousand words.
And was that other machine aN Arrow 1000 VMC with a A2100 controller.
Thanks John. Will try this on Wed. when I'm back into the shop. I like that tap cycle. And YES, the other machine "WAS" a Arrow 1000 with a 2100 controller, but it's been sold. But still keeping my eyes open for the spring. Thanks, John
You may want to go even larger say like 1250 C that would get another tweenty inches in "X" and I belive 3 more "Z". The digital drives and a few more horse power to the spindle and higher speed rapids.
John, to tell you the truth, the larger of the parts is 3.5" X 6.25". Another is like 2.0" x 21". Just making up fixture plate to do LOTS of parts at one time. On my 500, I have 2 different parts that I can do 60 parts at once. But the way the customer talking, going to need another machine. I wouldn't say no to a 1250. I was looking for a 1250 but the 1000 came up. Might even say YES to a 750, but would REALLY like a larger one. HOPEFULLY this will be talked about at the Friday meeting. Nice part is there ALL alum. parts for this customer, and talking about a 36 month contract. If these talks are fruitful, will have 2 machine BOOKED FULL TIME for the 36 months, with minimal down time for vac. time and maintaince. If the customers forcast is correct, I can not do his work with 2 Arrow 500's, that i do know. Have been fine tuning the programs for 2 of the 4 differeent parts, but without drawings as of yet, just measuring off of a sample part. Will keep my eyes and ears open, but nothing is finalized just yet. Just don't want to wait for the last minute and get cought cold, that's all. John
There are actual pallets that slide on and lock down with air, which would let you change out parts while the other pallet was running. The pallet set up we looked into required a giant window be cut into the right side of the machine through the sheet metal and a trck to roll in and out on. that sounds like it might would work for you, but for us we make six parts at a time with heavy machining = heavy vises.
John, I was/am planning on a pallet changer this way, ME. Simply use a 1" thick piece of alum., 26" X 21" woth dowels located on the both X+- and Y+, upper corners of the table, with the clamp slots for 4 1/2-13 bolts and T-nuts. with the thin Alum parts, thickest one being 5/8" but machined into the 1" alum, I can manually remove and replace, this would 60 parts every 4 hours. The 2 dowels, 1/4 and 3/16 would always locate the pallet, and the 4 bolts can be slide out of the way, lift of the alum. pallet with finished parts and replace with another pallet. Dowals located pallet and bolts slide back into place, tighten and go. Figure 2 pieces of 1" alum. 200 10-32 flat heads screws to hold parts down, some keys stock, and a few days of time, and I'm ready to go.
That's one od the reasons I want the fixture offsets to work. The guys who did my training is coming back later this months for any questions I have, but would use H30 for the 1/4" dowel so it's always ready to go. Would "tram" and set tools every week just to keep thing consistant. John
200 10-32 screws I am thinking screw gun for sure or you will have a very sore wrist.(LOL)
Use Some of the Carr Lane Round dowls and Diamond shape dowls with hardened bushing and should stay very close, especially if the dowls are at the furtherest most corners. I think .0015-.0025 repeat over 27 + inches is not a bad miss. alignment.
I think I would go with a few more hold downs in the mid of the fixture if allowable.
see on the VMC 1250 you could run two pallets at one time. come in the morning load machine push button and go to lunch come back at dinner reload push button goe home eat, you could run all three shifts by your self (HA hA ha, LoL) The bad part is thats how my boss thinks it should work. Hum then throw another machine are two in there and a good devorce Attorny, Volla you making money now. Or should I say the wife is getting the money now.
On the Training have the set the "OFSETS" Button up on the main home page. And nefently have them show you how to save the SETUP and TOOL page to the back up file under "part number/name" .bck and like I said 15 min. setups.

John, we are on the same page. Have discussed this with the wife as well. Send her in for the night shift LOL. I'm planning on a "screw gun" of some sort as well. Weather a small cordless drill with the torque setting or a air. But that # of screws was for 2 pallets. I think the round dowels will be good. We'll see if I need a center hold down but if needed I will use it. Just maybe if the four on the corner of the 1" alum. over 26 inches "might" be enough, if not, will fix it.
As for the 2 pallets on the 1250, would change over to run more parts at one time, or the two pallets. If this deal does go the way it's looking, and I get the 5 year contract, would consider putting the shop up at the house and be able to run round the clock and still be at home, IF NEEDED. Can work and see wife, hahaha. John
I will try to get some pics tomarrow night and through them at you for a look see.
I am sure if you see it once thats all it would take on the fixture off sets and back up files.
It defently sounds like it would be worth a set of dedicated tools for just the one job.
when done take every thing and place on a cart and lock it up that way all we be there next time needed, that realy makes it nice and neat.
How many years have you bin in the trade?
humm wife working with me??? sounds like a devorce to me. LOL
Vary much so with the dedicated tools. I have been thinking that way. Actually thinking of dupicate tools incase tgeres a problem in the middle of a run, just change tools #'s and go. Only looking like 10 so so tools per job, and 2 jobs are the same tools even.
This is my second go round as a tradesman. First was a millwright, but too dirty, so got into machining and moved into CNC from there. I have been doing CNC since '97. Machineing since '92. Graduated from millwright in '88.
But failed english in high-school LOL. Mostly moving job to job in the '90's, like every 12 to 18 months it seemed, but since 9-11 it's been more like every 6 to 10 months. Was running the CNC end of a shop up till April of this year and they got rid of everyone and started moving in people from there own country, India. This was a new plastic's company and looked vary promissing for about 10 months till a guy came with a large contract to manufacture window frames. He got in as 49% owner and everything went down hill from there. Within 38 days. At ther Christmas party there was 4? people, and by the second week of Feb. there was only 4 of those 4? left. I get along fine with those type of people from India and Pakistan, but this guy was just plain RUDE. His montra was " IF YOUR WHITE, YOUR NOT RIGHT". Nice for a boss Ya. All the skilled trade and people with knowledge were replace with imagrants from India for less than min. wage. I was even told by another Indian, that he was paying some machine operators $4.00/hr. PLUS they had to kick-back to him from that. JUST A MESS. So went back to work for myself. So far, NOT TOO BAD. Just need people/customers to pay on time and things would be good. John
