G-code help needed...
Does anyone who has 3D capable CAD/CAM have the ambition to generate some G-code for me? What I need is two sets of code for a half egg shape, a positive and a negative to use in a press. The egg would be approximately 3.5" diameter by a suitable length perhaps ~4.5" or so. The pos/neg die clearance should be .020". Post processor for Mach3. Thanks, Pete C. |

It seems that some commercial molds are available for very big eggs or for small eggs, but not mid sized ones. I'm planning to laminate up some oak or similar to mill the dies out of, add some guide pins and then press the pan halves out of aluminum flashing material (~.015"). I've got 1/8", 1/4" and 3/4" ball end mills on hand, along with the usual assortment of regular end mills for roughing. I'll be running this on my little CNC'd X2 mill since I haven't found an "Iggy" deal on a larger CNC mill to refit yet. Thanks, Pete C. |

Do you have a sketch? -- John R. Carroll No sketch really, just a moderately large egg shape cut in half axially, so that two pans pressed out with the die set can be clamped together to bake a solid egg. |

Carroll That sounds like a good size, and one that should fit the small work envelope of an X2 mill. Also the 1.75" draw depth should hopefully be small enough that the AL flashing material will press ok. I've got a basic 20T H press which should do the job. Since this is to bake cake which will get frosted, the surface finish doesn't have to be perfect. |

Carroll aux34 at snet dot net I have TurboCAD, so I can view a variety of 3D models, it's the 3D CAM that I'm lacking, I use SheetCAM. Thanks, Pete C. |

I would help, but it sounds like you already have better qualified helpers than me. Laminated hardwood stamp and die huh? Interesting. I take it that it will be a modestly small production run then? |

Carroll That looks perfect. I'll glue up blocks that are 7.5"x12"x3" thick or so to mill the die halves in. It looks like it should be millable with the 3/4" ball mill I have possibly? Perhaps roughing with a 1/2" EM? My X2 will do ~2,500 RPM and about 30 IPM. Thanks, Pete C. |

I'm hoping oak will be sufficient (backed by 3/4" steel press plates) to form relatively soft AL flashing at the 1.75" depth needed. If it works well, I wouldn't expect to press more than a couple dozen pieces or so. |

Carroll At about .015" the AL flashing material is relatively thin and soft yet should be solid enough to be reasonably durable, hopefully it will behave ok. |

Its 149 dollars for CamBam and it does decent 3D 3 axis CAM. Not great, but not bad, and its 2D / 2.5D is impeccable with some really nice features for nesting multiple parts in the newest release. Its even starting to implement some rudimentary speed feed stuff. Also you can download and try the latest version totally for free. Its 40 executions limited (which is better than time limited in my opinion) so you can set it down if you get busy and get back to a project weeks later, and you haven't lost any of your demo time. It is not crippled in anyway. There is also a free version, but the free version is strictly 2.5D. I don't think the free version is all that great, but its free. LOL. Anyway, don't waste your time downloading the free version. Just download the latest full release. When I did I made a lot of parts during my demo period. On the flip side SheetCam does look like clean basic CAM for 2.5D. On the flip / flip side you did get working code for your application even faster by using RCM CAM. LOL. It takes a little while to learn everything in CamBam, but it is beginning to become quite capable of some fairly complex work. |

It is not crippled in anyway. There is also a free version, but the free version is strictly 2.5D. I don't think the free version is all that great, but its free. LOL. Anyway, don't waste your time downloading the free version. Just download the latest full release. When I did I made a lot of parts during my demo period. On the flip side SheetCam does look like clean basic CAM for 2.5D. On the flip / flip side you did get working code for your application even faster by using RCM CAM. LOL. It takes a little while to learn everything in CamBam, but it is beginning to become quite capable of some fairly complex work. I've got FreeMill now and will be looking at it and trying to learn it as time permits. It appears it should do the job once I learn it. As for SheetCAM, it has worked nicely for the plasma and milling I've done up to now. It's probably been helpful learning CAM stuff on 2.5D to keep it simple. |

G-code help needed... *Update*
"Pete C." wrote: Does anyone who has 3D capable CAD/CAM have the ambition to generate some G-code for me? What I need is two sets of code for a half egg shape, a positive and a negative to use in a press. The egg would be approximately 3.5" diameter by a suitable length perhaps ~4.5" or so. The pos/neg die clearance should be .020". Post processor for Mach3. Thanks, Pete C. With John's help I was able to get the two die halves milled nicely. My initial tests with the AL flashing material showed tearing issues, so I'll need to search for better material. I did have a scrap of 30ga galv steel on hand so I gave that a try and it formed reasonably well without tearing, so the basic die set seems to be workable. |

I was wondering how your baking tin project went. |
