In 1985 the shop I worked at bought EZ-CAM software on an Apple McIntosh. I loved it. I had to program a Bridgeport BOSS V control and a Heidenhain control. I modified the BOSS V post to create code...

The two links I included seem to imply an absolute encoder doesn't require power to maintain position knowledge. They both say an absolute encoder knows where it is at power up.
If it requires power...

Did you get this figured out?

David, may I purchase a copy of the parts manual from you? If not, can you give me a part number so I can try to get a part from South Bend?
I called South Bend today. They said my lathe is too old....

Thanks for the attention to this.
Orchid just replied to me to tell me it should be fixed in the 2015 Beta that will be out in about a month.

Guys,
I am a long time user of VX/ZW3D. I am not using the 2015 version. I need to translate some V5 CATIA files for a RFQ. I downloaded and am now using the trial version of the latest 2015 as of...

just saw this - have you figured it out?

I would think about shimming the Y axis blocks for a while before doing it. I don't think it is the same as adjusting the Z axis guide.
What you want to do is align the machine components with the...

How far out are each?
I think a 6 inch machinst square would work very nicely for your machine.
An ajustment of the Z blocks will not affect motion but will affect the tool axis squareness.
The...

good point - I did assume the asker is competent to do the adjustments I suggested.
On that vein

Hyrum - how did you determine the machine guides are out of square?
What do you have to determine...

underthetire - I will agree.
About the only reason to worry about level is to get the coolant to drain in the correct direction. :)

Not sure why you would think this way.
We have done this on our three Haas mills (VR11, VF10, VF6) and have been VERY pleased with the results.
As far as I know, we have only done it once to each...

I think the answer is yes.

Loosen the Y axis blocks under the saddle that runs on the Y axis guides. This will allow you to adjust the X axis so it is square with the Y axis.
That machine looks...

Thanks for bringing up the first thing to check when you find a machine not positioning correctly. I forgot to mention it.
When a problem presents itself "level" should almost always be the first...

Don't think of it as Y is out of square with X. Think of it as X is out of square with Y. The Y is not adjustable. You can do this without a technician. Follow the procedure outlined in the first...

As previously noted - opinions are many.
In my opinion NCL from NCCS is the ultimate CAM system. NCL will cut anything in any way you want. NCL is expensive. NCL has a long learning curve.

You are correct to assume most 5 axis machines move point/vector to point/vector - one line at a time. Assuming the tool tip describes the programmed path is not correct. Some CAM system allow the...

Our AS9100 states that we check the coolant concentration and ph daily and adjust as necessary.
Concentration within coolant manufacturer recommended specs.
PH at 8 to 8.5
We have logs to show...

Rocky,
To answer a couple of your questions.

I bore the taper to give me .0004 (.0002 per side) clearance.
The interface area runs from .125 to .375 top and bottom.

I agree with your...

Rocky Russell,
If you will look at your records for late 1999 or 2000 or early 2001 you will see Spindle Grinding Service was in Wichita at a shop for one afternoon and the next day. Your grinding...

I have Fadals also. No problem with tools sticking in the Fadal spindle tapers.
I was very hesitant at first. I had the insert made for six months or a year before installing the first one. Like you...

I must agree .010114 is too much.
I must disagree .0004 is the correct amount.
The correct calculation is in a post above.
The correct calculation is approximately equal to my observe measurement.

To answer the question about changing spindle bearing preloads. I wondered about that at first. That is one of the reasons why I let the first machine run for a year before doing the second machine....

Sorry about the almost double post here - I picked the incorrect column to choose my coefficient - I was/am wrong
I chose the metric at .000013 and should have had the 'not' metric at .0000073
...

math

given the thermal expansion of steel is .000013 inches per inch per degree
then a 2 inch diameter would shrink/expand .000026 inches per degree

given the temperature of liquid nitrogen is...

sorry about the double post
I have not done the math but I have measured a lot of the inserts. .006 shrink is what I measure

Spindle body deformation is the reason for less the .002 press fit.
I always use liquid nitrogen and always drive the insert in with the Z axis. At first I would push it in by hand (with gloves)....

In all honesty - any machinist could build the insert and then install it. heh
I build mine from S7. Saw to length, face to length and drill a through hole, heat treat, wire edm the taper, grind the...
