I should have posted this before, but I thought I could go back and edit my original post. You can find the compiled "manual" here. Work in progress...

General Safety Manual for Machine Shops

I was very careful to not scratch the surface plate.

It's interesting comment about the inserts being coplanar. How should one usually install inserts? I was told to that they align themselves but...

Should I not be using it for what I am then? Ensuring inserts on a face mill are parallel while tightening?

Thanks, that's it!

How are these used? It says for measurement and reference but what does that mean exactly?

No help from wikipedia either.

I'm not sure what these things are called otherwise I would just google it. We have a few granite blocks that I am told are very high-precision. We also have a granite slab and "high-precision"...

Wouldn't they just do a shrink fit instead of a press fit for something like that?

I've only used a HAAS. What do the competitor's do on power-up?

I've been quite surprised at how strong this freeman wax is. I have two grades, the medium hard and the very hard wax.

If you recall this part was made out of the medium wax. The flange is only...

I really appreciate this great info guys. If your are ever in Raleigh or if I visit Canada again (used to live in Michigan) the beer's on me.

Sorry if my stock material question was confusing;...

"Wrong section error"? Don't think I've ever seen that one before.

Oh yeah, any comments on my problem with stock material? Thanks.

I'm not seeing the advantage then of using 1 bolt then. I still have to make a fixture either way. Plus, it seems to me there is a risk of damaging the bearing surface for the shaft on the housing by...

Well I did some googling. I was imagining a woodruff key to be something else. Basically there would be 3 pieces then right? The shaft, the rotor, and the key. I was thinking there were only 2...

Geof,

I'm liking the press-fit idea. But I was avoiding the keying because I was unsure of how to cut one in the shaft.



Indeed :D But I wanted to try something that required me touching...

pointcloud,

Not sure if you saw the edit after my last post. I may consider turning the shafts and milling the rotor.

The pump may be smaller than it looks. The inlets have a diameter of .91"...

Yes, the shaft and rotor are all one piece milled in two steps... or that was the plan. I didn't mention it, but my only successful try with this setup the shaft on the other side was indeed...

Thanks Geof. Wedging caused by the vise definitely makes sense - I think intuitively I knew that. So it sounds like the second design of the rotor fixture held together with screws might work?


...

Nice! Really wish my employer had bought the enclosure. It makes a mess otherwise.

First thing I do is turn off the safety switch override. The spindle warmup won't run otherwise unless I am there...

I'm new to machining and I have been searching around about fixturing techniques for CNC milling. Unfortunately, there does not seem to be a lot of solid information on it. The basic idea as I...

hey guys. Thanks for the responses. On vacation w/ my girlfriend - she'd kill me if she knew i was online. :D

I read that article in CNC magazine, and the filtering and cut tolerances did the...

Thanks Geof, good stuff. I will play around with the cut tolerance and the filtering.

It definitely was not using G2/G3. You could see it running through many lines of XY coords around the corner...

The flat along the outer edge there (pic 3) is just an optical illusion, it's actually quite smooth as it was face milled.

My chip per tooth was .0083 and my feeds and speed were as high as I...

Apologies for posting this problem again, but I was not getting much response in the Mastercam forum. I want to open this question up in a general sense.

Basically, I am using Mastercam and it is...

JerryFlyGuy, under-dog,



Our small, in-house laser is from Universal Laser Systems. All of their systems are driven by print drivers and the only software they endorse is Corel Draw. I think...

The mill I run is in an environment around others who do not know how to operate the machine. So whenever they could be around (normal business hours) I make extra sure I don't leave it unattended.
...

PDFs also work really well for laser cutting that is not CNC but uses print drivers. Importing DXFs into Corel Draw is usually a pain.

You lost me. "it puts them all on the centerline of the sketch" is a bit ambiguous in terms of 3D space. I can't quite visualise the web of material thing either. A picture or even the drawing files...

I usually run into this when a face of the cut is tangent to a face in the body being cut.

For instance, draw two circles sketches, one with a smaller diameter and tangent to the inside of the...

I know you didn't say they give out the info. But others have said techs either did it for them or told them how. I don't recall if it was even in this thread, maybe one of the older threads I...

I may not know what I am talking about, but I've read this about straight flute endmills:

Used for light cuts on very hard and abrasive ferrous materials, and also for use on thin...
