Cambam thread milling
Last I can tell it how far above the platen surface I want the taper to begin.you would think of this height as the die land height if you're making punch dies.Īll of these commands are simple inputs and I believe all wires capable of cutting tapers will have a screen like this. Then I can tell it how I want to instruct the machine, whether to use the "A" word, Complex Upper and Lower, or command the U and V axes directly. Using my Chmer again as an example, I have a taper set screen in which I can input first of all that there will be a taper, and what it's angle will be. In addition to the code, you also have to set up the machine, and this is typically done on some kind of taper setting screen in the control.

I am not sure if every wire machine out there can do this but I see it relatively rarely in sample code so I suspect not. This is called "Complex Upper And Lower" programming (by Sodick which was the machine on which I first learned it) and is used when the taper varies as you go around the profile. There is another way however, and that is to write the code for the upper profile, write the code for the lower profile and stitch them together line by line. On my Chmer machine which will run from the code created by a standard Fanuc post, the command to begin the taper is "A" followed by the taper angle desired (positive or negative value depending on whether you want the big end at the top or bottom of the part.Įvery different machine brand seems to use its own unique word, so "A" may or may not work on your Fanuc.įor the majority of taper work on punch dies this is how it's done by pretty much every machine I've seen code for. My experience with different brands of EDM machines is not very wide, but on all I have run, the most common command to run a simple non-varying taper is created by inserting a taper command word into the beginning of the code string and a taper cancel word into the end of the code string. If you're already into CNC milling, I'd first see if my milling CAM solution could be made to work. Wire work is typically super accurate work and the gremlins that give you the ass bite are not usually the ''s the operations order and the stock allowance and the fixturing, and the stress release and the overcut allowance and the flushing and etc etc etc. Programming on a wire is not very demanding it's setting up and processing strategy that is the big differentiator in wire work. I run an old old version of Mastercam Mill (version 8.1 not X8!!) and just call my cutter 0.010" diameter.Ī buddy of mine runs Bobcad and says it works fine for him too.Īnother buddy swears by Esprit, but he pays a LOT for the bragging rights and I don't think his parts are any more complicated than mine. Assuming your machine eats G code like every other Fanuc machine in creation, you have a huge variety of choices that will work.Īll you need is a post processor that will speak "Fanuc".
