Pictures of things made in Home Shop CNC

[TomS]

Tom, I make emblems that have lettering and designs similar to the lettering on your fuel cap. The "tails" I experience are usually from wayward entry and/or exit settings of the cutter. So much so that a lot of the time I just slow the feed rate way down and do not use a ramp (helix, 3D path, etc) entry at all - just plunge at each level. For some of the fine detail I am using a high-speed spindle with end-mills in the neighborhood of 0.010", so easy entry is important.

USMC emblem is about 2.25" diameter

As a side note, I've managed to figure out ways to powder coat the designs instead of paint. Makes for a very durable product. Finish is usually either satin, burnished or polished to a chrome-like surface.

I think you hit on it. I had "tangent with a .125" radius" set as my leadout setting. I'll play with it in the morning.

Couldn't open your attachment. I get a forum failure error.

Attachment is just a picture of an emblem I made. Am I doing something wrong when I add the image to the post?

This is the error I'm getting.

I made an album to save the picture in instead of saving it to "members area" as I have before. I just noticed that the album is not for public viewing and I don't know how to make it public. So I moved it to the members area. Can someone tell me how to make my album public?

not a whole lot of CNC lathe work here. Lets see if we can change that. Finished up a stainless shift knob for my buddies GTI today.



had to make a split collar to hold it for the second operation

Had a slow day in the shop so I thought it would be a good idea to setup my tool rack with a numbering system. I rarely have a job that takes more than four tools but it's always in the back of my mind that I not pick up the incorrect tool. Having them in a numbered rack hopefully will lessen the likelyhood that will happen.

Tags are 1/16" x 9/16" x 1-3/8" held in with a couple of #6 screws.

Tom, I do the exact same thing with my tool holder. You may want to go one step further if you have a standard tool numbering and write the number of the tool on the holder as well. It's a good back-up in case "someone" puts a holder back in the wrong spot.

I've been watching the Fusion 360 video tutorials and playing around with it for a couple of months with the intent of learning enough to do some 3D machining. I finally got to where I can generate workable gcode. Here's a few pictures of my first attempt.

Tom S.

The two holes are not intentional. I used material from my scrap box and the holes were already there. I had tried some code at 1" total stepdown that didn't work out so well. This attempt was done at 1/2" total stepdown. That's why there are machining lines lines that show up just below the edge radius.


I roughed out the general shape with a 1/4" carbide end mill leaving .020" all around, then followed up with a 3/8" ball end mill semi-finishing pass taking .015" DOC. Finish pass was with the same ball end mill at .005" DOC.


The finish could have been smoother. Still learning!

Looks good for the first attempt.

very nice and inspiring.
