Any news on the new release as far as date and new features?
Thanks,

Hi,
How does the "skin" function differ from cutting down towards the bottom of the part but leaving 0.020 on the bottom? I don't really understand the function.
0.020 would certainly hold the...

Everything 6 inches or less, no steel, needs to be mobile...

Get a Taig unit. I have one, and move it around easily by myself.

Sorry, I know its the Tormach forum, but my thought while reading...

Setting the start point of part cutting...

I have since found out another helpful item. Sometimes you want to define where to start cutting a part. If you are outline milling along a closed...

Hi,

I ran my first parts on Madcam, and was very happy with the results. See pics below:

A couple of real time savers that I learned:

- Use the rhino trim function to create part tabs...

From you second post, it sounds like something is getting shorted to the mill, or its some sort of ground problem. Perhaps try a heavy frame ground wire from the motors to the mill, or even to the...

From what I understand in your original post:

Things were working fine, and then you rerouted (cleaned up) all your wires, and then you had erratic operation in your motors.

This sounds to me...

Hi,

Rhinoceros (www.rhino3d.com). Not really a competitor to Bobcad anyway. I would think its a common function in CAD software these days. Bobcad is more of a CAM program, but it may have the...

In a different program that I use, you can automatically generate 2D drawings from solids. Not sure if BC has that feature, but I can see where it sure saves a lot of time.

A final note...run all your roughing passes first, and then your finish passes (all the way around). Saves a lot of manual tool changes.

If you are running Madcam using very small cutters, and you are not getting toolpaths or very short toolpaths, you need to reduce your cutter tolerance. I set tolerance on a 0.005 ball nose to...

Not CAM related, but if I were a math guy looking for software to write, I think I would take a crack at the PCB autorouter market. There has been a lot of consolidation in that market, and there...

It struck me on the way in to work today...

It is not too hard to index the rotary table with a G1 A 45, 90, 135, etc. So it is probably easier to compute the machining for the first segment, and...

And then you could finish up with a 4th axis finish pass. Not sure if this is needed, but I think it might be useful to save some of the indexed machining. ie, maybe run this and then run pencil z...

Hello,

I have been practicing more with Madcam, and am going to try to machine a ring in wax using my new rotary axis (taig setup). These operations might seem obvious to a veteran, but for me, I...

PS: When I say perfect holes, these were cut in wax, so there is no machine loading. I did notice more hole distortion when cut in AL sheet. But I figured out it was my clamping and some flex in...

No, I didnt lap the ways, as I'm sure that is beyond my skill level to do it well. I'm actually much more of a tech geek than machinist, but I'm getting there. I also don't think my machine needs...

This is useful info if you want to engrave text on a cylinder.

Rotational machining on a cylinder using 3D operations like engraving text is called "Y axis wrapping". I tested a real nice freeware...

Not leaving well enough alone, I went back and attempted to adjust the backlash again . I was quite happy with the result.

Adjusted both x and y backlash. Was able to about 2/3 mil (0.7 mil)...

Hello,

I measured and adjusted my backlash this evening on my taig cnc mill. I bought the mill 4 years ago, but am just not starting to really use it. I had searched on here yesterday to get an...

I find out a bit more info by experimenting.

A slightly more efficient way to rough the cylinder (cutouts) is to use bounding curves for the machining (region curves). You can add, for example,...

Does Rhinocam provide G2/G3 for 3D model toolpaths as well as 2.5D?

I had been looking at this also a few days ago.

Here is a related thread in the general CAM discussions:
...

After some reading, the whole G2/G3 (circular interp) -vs- G0/G1 moves (tiny straight lines) is sort of tied to the machine controller (mach3 in my case) and its implementation of CV motion (constant...

Pasted below is what the developer of MAdcam (Joakim) replied to the same question in the MAdcam forum. I tried the suggestions and did see improvement, but there are still miniature line sigments....

Take another look at madcam. I have been running it now for a few days and am very happy. My opinion so far is that it may not do "quite" as much as rhinocam, but I havent really found it yet...

I too noticed the same thing with Rhino4.0 and Madcam. Ive just been using the software for a couple of days. I was about to post a question, but found this post. I havent investigated yet, but...

Hi,

Have been continuing to test out Madcam. So far, it has been very stable. No crashes yet! Have even cut a few parts in wax.

I have been running it on just about any 2D/3D object I can...

Hello,

I recently purchased madcam, and have been investigating its capabilities. I have a Taig mill with 4th axis rotary table. In evaluating the software, it appeared to me cylinder machining...
