Wow.. that mold is awesome.
Made on your CNC .. it look so smooth..

very cool when you gonna get walking its an agonising wait to see it in action

Thanks Guys

As for walking, hopefully by the end of the year? I am hoping to have the body done and the robot 90% assembled within about two weeks. I could at least make it stand for you

Here's a better pic of one of the body mold positives. A little more contrast.

What are you using to make the mold... pictures of the process..???

The material I cut it from is Prolab 65. It's a medium density prototyping board, like a dense foam with similar weight to MDF but holds detail much better.

I'll try to get some pics of the process up tonight when I get home.

So, DialFonzo, this may not be exactly what you're looking for, but it's from the beginning.

First, a tour of my spacious 14 sq. ft. shop.Yeah, that's it.

Step 1: DesignI'm going to follow the production of the highlighted part.

Step 2: Create a mold cavity with a 5-6mm margin from the part. I cut it close in this case due to space constrictions. For each case I will make the mold walls at least 3mm taller than the part. As long as you cast on a flat surface then this margin isn't extremely important.

Step 3: Mate the parts, set origin according to the CAM program you use.

Step 4: Create CAM profiles. Honestly, my mill is nothing to write home about. Rigidity is not a strong point. Smart tool paths are the key.Rough at reasonable margins and finish with levels that you've experimented with and know produce good results.

Step 5: MachineA shot taken during the final finishing cut creating the filet on the edge.

Step 6: Finished Mold The explanation ends here for now. I'm still waiting on some parts so I'll discuss the silicone and polyurethane casting afterwards.

Hi Marcham,

That is an amazingly compact shop considering the quality of the molds you are able to produce. How do you manage to keep your computer components from choking on the dust you produce?

I have done a lot of latex and resin molding and casting for my garden railroad buildings, and I used to do a lot of 3D plague routing in my woodworking days. So I am familiar with the general processes involved. I am very interested in your CNC machine. Would you point me at some information about it?

Thanks, Ted

hello,

I bow to a Cad skill far greater to my own, you said in previous posts that you use solidworks is the program you are using for the cnc machine and your lastest designs, I use Turbocad could you post your files so that i could try to import them into Turbocad i would love to see a manipulable projection

Thanks guys!


Haha, I pretty much just let it choke. I vacuum quite a bit but the tiny chips that come off while finishing still get everywhere. Every once in a while I'll give it a good blast with canned air.

For info on the mill check out http://www.zentoolworks.com There is plenty of online support for getting the thing up and running and the customer service is very good.

Thanks, man. I'll post when I get home tonight.

Great work man!
Thanks for explaining your methods. This is very interesting.

Hey Thanks Guys!

I'll try to get the second half of the process up on here next week. Then hopefully I'll be finished molding my parts around the same time.

Xan, check out www.zentoolworks.com . I pointed them out to Ted above. Reasonably priced kits.

Sorry I didn't post the parts last night codemaster. I'll try to remember tonight.

Very nice..
I want to do a mold now..!!!
