Could you please answer me this question? Actually my family business is coin manufacturer especially making Buddhist amulet coin. My father is traditional hand engraver. He doesn't use the epoxy machine but engraves directly into the die. The problem is NO ONE in my family can do like him. I want to use the CNC machine for creating die. But I want the machine that can make the negative die which ready to stamp it. Does anyone here know how to solve my problem? The best thing I really want is Just scan the photo and then engrave the 3D negative die If there is no such the thing I said, please suggest me anything that you think it is the better way for me. I will learn how to use the 3D program next month. Hope it could help my family. I'm Thai so sorry for my bad English. Thank you very much in advance!
It would be best to contact someone with a LOT of knowledge on this subject, and that would be Daniel Carr. He's a member of this forum, but you can email him directly through his website and he WILL reply. Let him know you're a member of CoinTalk. Here's a link to his site: http://www.dc-coin.com/
Hi, I would recommend this magazine ( it is both paper and electronic issues) as it seems better suited to your stated intentions than many of the higher end machines which are beyond most small businesses financial ability. http://www.digitalmachinist.net/ On the main page , there is an Interactive page TAB, that has G-code downloads of the projects that have occurred in their magazine, a forum similar to ours that concentrates on aspects of CNC, etc. and other goodies. That forum would probably have better overall answers than us I enjoy reading through it as my family depletes charge cards in Barnes and Nobles bookstores, Occasionally, an article is so interesting I buy the paper issue.

Could you post some images of your fathers work? I would love to see some of the traditional techniques at work. Thanks and welcome to CT.
Those are absolutely beautiful. It would be hard to recreate the skill of craftsmanship displayed on these pieces with modern machines. Work like that demands a personal touch.
Machines can be used to rough out the design, and then hand work done to finish the die. If a fault occurs in the production of the die, it is easy to replicate the "roughing in" part and reduce the amount of work needed. Many jewelry items such as individualized rings are done by digital machines for the rough shape , and then can be modified if the size of the stone is lightly off before lost wax casting in PM. One nice aspect is that a design could be done in a 3dCad program in the positive aspect, wax printed to see what the design looks like when finished, and when as desired, reverse the image to the negative and machine the steel die for production after small details are cut by hand or dental hand piece and polished. IMO. Jim
