Hi everyone. I need to find out how to get a G-code for a custom sinnk we are making. The toolpathing software from AXYZ allows for a sloped cut, but not a four-way sloped cut. Here is an image I drew to give you an idea of what I'm looking for:   |

If anyone wants to job out the G code, that would be fine too. |

On the AXYZ router that I used to run you could set slopes on different layers. Have you tried separating the shapes and setting individual toolpaths for each sloped section? It could also be possible to run 4 different programs as long as you leave the piece in the same position and keep your absolute zero in the same point. |

Interesting, Brian. I will look into that. You color coded them into the layers anbd worked each one separate without moving the piece, allowing your F13 start point to be the same? |

I don't have the AXYZ, but what Brian said would work the best. After routing you are going to sand smooth anyway, so if there is a bit of imperfection where each piece comes together, not big deal.

Tom,
Brian has a good idea about creating separate programs for each individual slope. Before I learned how to rout 3D objects on our CNC, I created a couple programs by figuring out where to run a 3/4" diameter core box tool to rout the slope in several steps. I have attached a drawing (in JPEG format) showing somewhat what I mean. This could take awhile, but if you're planning on making several of these, it could be worth it.
Have a nice evening,

Andy, Brian and Seth:
Thanks all for the good ideas. The problem I have with the four way method is I will have to route four separate pieces, then glue them together. Does anyone think there will be a problem with this? It will get backed up by the bottom piece, so I am inclined to think no biggie, but I'm not sure.
Problem number two:
Only one sink is as shown. The other two have an offset drain that means there will be different size pieces running along the edges of each other, so I am afraid the slope and thickness will be different for each piece. Am I right in thinking that way, and is there a solution? |

I didn't really think of making separate pieces and then gluing them together. It was my impression that you would have a piece of material that is thick enough and you would mill the whole thing down.
I would make 4 separate closed shapes. Do a 3-d fill on each one individually, and then do the slope on each one of those fills. That can get a little tricky because if you miss a line on the slope it's going to cut at the wrong depth. That would be the reason for splitting up each section into a separate program. If you do that then you can just select everything in quadrant 1, run the program, and then move on to quadrant 2. |

Here's an exaggerated drawing of what I'm talking about as far as making 4 separate closed shapes. In reality the shapes would probably only be about 1/32 apart.  |

Brian, I might be wrong on tis, but my impression is if I separate the items into groups (that's what it's called on my toolpath software) it will over route into the other areas. When we slope drainboards, etc., we make sure we clean the route by running past the piece at least by the diameter of the bit. That would render a one-piece shot here out of contention, would it not?
Sorry for being a moron on this, but I'm having some trouble wrapping my head around your idea.
Thanks for staying with me on this. |

Reiterating my comment from last night, I also only have one sink like this, where the hole is evenly centered. I alsohave two that are offset in the drain position. |

As long as you set your cutter compensation in Toolpath it will cut along the inside of the line. If you're worried about how the different quadrants butt into each other then you could just do a straight line with a core box bit (which you should probably be using for this in the first place) right down the middle of the quadrants to clean them up...something like this would work.  |

This is a rough sketch of what the final drawing would look like. All of the lines would be closer together though for more tool overlap. If you want to run separate programs then I would turn off all of the layers but the red one. Do the 2-d fill, set up the slope, and save it. Then I would turn on the green layer, do the 2-d fill...and so on. Hopefully this picture helps a little more.  |

Brian,
You are awesome for staying with me on this. Let me run this by my partner and see if it makes sense. |

So what's the word on the sink? |

Still working on it. Thanks for asking. |

If some one wants, I can send the process to them in more detail

Just to add to the mix of custom sinks...
We do custom shower pans for some customers in EOS.
Since I've been told that our machine will not do slopes other than in a straight line, we came up with this method.
We will do our shower pans in several steps using the grouping of colors to contol our depth.
Our fabricator then sands down the steps that the tool creates and cuts the hole for the drain using a template and a router.
A little crude but it works.
A cleaner way to do it is on our Intermac machines we use for granite
All you have to do there, is set up a border and your drain hole, set the total depth, and the machine does the rest. A lot quicker to draw, a much cleaner job and no dust since it uses water.

cismon,
I'm open and gratefull to all ideas.
You can get to me at:
info"at"mathertops"dot"com
replace the "at" with @ and the "dot" with . .
Thank you again for the offer.
I have been thinking about getting artcam or somesuch for awhile now, but it's hard to justify it for a job or two. |
