If you have a working copy of the post file, could you please post a copy of it here, so I can review its contents. I had attempted all of these edits and then some though, all at one go, so I was unsure if that one place is the only failure cause. And the "onOpen" routine failed, which is where that variable is being used, per the instructions above. One of the things it said was that the "gUnitModal" is not defined, which I found to be true after looking the file over (I have years of iLogic & vb.net coding experience)(not sure exactly what format this file is in). I was trying to follow the steps shown above to edit a copy of my multicam.cps file, but I found that the resulting post from Inventor CAM using the renamed, edited post file failed with errors upon opening the file afterwords in a text editor. I even downloaded the latest version from Autodesk's CAM site, which was a year newer, but that did not seem to fix anything. Pretty much all the same exact stuff you mentioned were the differences in the two resulting cnc program files. The default 'multicam ISO.cps post processor that comes pre-loaded in Inventor CAM was definitely not outputting the ".cnc" file the same as our EnRoute software was, and we knew that the EnRoute programs were correct. After a few weeks, we wanted all 3 engineers in our team to be able to write programs for it, but did not want to buy more seats of EnRoute, because we all already had access to Inventor CAM Ultimate 2022, so we wanted to use that as a back-up/alternative. Our company recently got a second hand 2017 MultiCAM 3000 Series CNC router, and a single seat of EnRoute 7 Plus for creating programs for it. This post actually sounds like an exact match to my needs also. Save the post processor and test the code guys. Y0 in the footer instead of G98 P147 D1 : Add following code in function onClose //writeRetract(X, Y) the current post does not insert a G70 in the header : Add switch in function onOpen, switch (unit) ) Ĥ. 2Flutes should have half the rpm of a 1flute endmill.Hi would suggest you to refer Fanuc post processor for the current post modification request.ġ. So what I’m asking is, is there some formula or rules that we apply to make feeds/speeds work or be in the correct ball park.Įg. But yet other similar machines are using 24k rpm for same endmills. That when I purchase endmills, i have the recommended feeds/speeds, but they seem way off the charts that my machine can handle, so I’m basically just guessing figures until it sounds right.Įveryone says I should only be using 10-16k rpm max. You can also compare different solutions and save your results for future reference. Like I’m at a stage (mind you I’m new to this game). Do you need to find the best tool and cutting data for your machining operations Try the Sandvik Coromant CoroPlus® ToolGuide, a web-based application that helps you select the right tool and optimize the cutting parameters for your material and operation. ![]() ![]() How does everyone work out their starting feeds/speeds when they first get an endmill and are given parameters for the endmill bit? Like is there a rule to start off with based on endmill parameters. I’m guessing this is because either the lowrider speeds can’t travel this fast and rigidness, which is fine.īut how do I go about using these high parameters and making them work on my machine without actually trying it. Such a big difference in their feeds/speeds. Their recommendations are 33mm/s, 24000rpm, plunge of 3.6mm/s for use on a SharpCNC. Now if I purchase the same equivalent endmill locally, Now this is pretty much the safe zone for that as advised. Most speeds/feeds are very high, even for small cnc’s and hobby cnc’s.Īn example is for the v1e 1/8” 2F downcut I’m getting recommendations of 12mm/s, 10-16K rpm, plunge of 3-6mms. ![]() My question is, when I purchase an endmill. I know this question has been asked many times, and that every machine is different.
