Parametrics and MDF doors2/7
I need to make MDF doors and have some questions.
It looks easy enough to program a door parametrically on the machine control but it seems to me that it would only work 1 door at a time.
Is there any way to open a dxf file of nested rectangles and apply the parametric program to each rectangle on a nested sheet?
In vCarve pro, You could draw one rectangle, then create a toolpath template that runs the various tools at various depths and offsets from that one rectangle. Now save this as a template.
Now load/draw all your rectangles and apply the template to all of them.
This would likely only work for squares and rectangles, so forget about cathedral arches etc, but it should get you some basic square doors.
Beyond that, you need to look at one of the MDF door programs.
Are they all the same size and style? How many do you have to make?
Different styles and different sizes, but mostly flat panel styles.
I'd like to make as many as I can.
Give Vcarve or Aspire a shot.
You can either import all your "squares" for the outside size of the door, or draw them all in. This should be a very quick process.
You can then run your tooling with offsets from that "square" to create the rails/stiles.
If you need more control than that, you can select all your "squares", then use the offset command and it will draw a bunch of "squares" within the original "squares" to a set distance.
Use layers and toolpath templates and this should go very fast.
I'm not sure what cam program your using but Biesseworks will let you open a DXF file and then assign toolpaths to the lines of the drawing.
You can also create toolpaths with layers in autocad or one of the clones if you know what you are doing.
It seems to me like setting variables of width and height and then setting the value for each door would be easier than the work of doing it in CAD.
I could show you some parametric scripting work in Autocad that very quickly generates all you need to batch process an unlimited amount of doors a day (well limited only by machine time)
If you're so inclined
