Machining my new CNC Z axis assembly aluminum base plate

- This video summarizes the CAD and CAM of my new Z axis assembly, focusing on the machining of the first aluminum part - the base plate which will attach to the X axis gantry of my Onefinity Woodworker X50 CNC router.
I provide details of the machining setup, toolpaths, machining parameters, and sample video clips of all the machining.
A few things to take note of:
1) Video playback includes real-time and increased speeds - in some cases up to 6 and 8X
2) The 'feeds and speeds' presented were at times modified depending on the sound of the cut and chips produced. In most cases this involved lowering the feed rate.
3)The endmills I used from SpeTool, Datron, and YG-1 all performed extremely well. The chip-welding I experienced using the 3 flute YG-1 for adaptive clearing was most likely a function of incorrect machining parameters - something I look forward to experimenting with and improving on later.
4) Although I have an MQL setup, I prefer to not use coolant at this time, and have found a strong air blast clears chips very well.
how are you fairing with slotting? I've opted for adaptive clearing a slot a little larger than the tool diameter just cause my machine isn't very rigid
Slotting is not my first choice, but with very shallow DOC, monitoring and adjusting feed rate and RPM, and plenty of air to evacuate chips it actually worked quite well. I also like adaptive, and used it for my plates - I just today finished the top plate and the adaptive worked very well. In the past I would have used one of my saws to get the stock to a size closer to my part, then used contours mostly after that. But I don't have a shop, and found the chips are better contained on my CNC than in my back yard or basement where they used to fly everywhere (-:
@@tmtoronto3741 Hi yeh well we all know the pit falls to slotting But I have been 6mm and 8mm slotting 6061 alloy to an 8mm depth using ramping with great results using mist coolant and air blast also wood to 20mm deep though it get harder to clear the chips after 17mm, thanks for putting out this video Cheers Bill from Australia
@@williamnorris1516 I appreciate the kind words! Speaking of slotting, in my last video put up yesterday, I share a clip of an 'oops' moment where I chose not to run a simulation - which I always do BTW. At the finish of a 2D adaptive at 4 mm DOC my 1/4" O Flute finished plowed through to position the start of the next pocket. I hit Feed Hold quickly, and nothing broke, and it gave me a great slo-mo shot to share of the chips flying at ~ the 4:33 minute mark in the video! How we learn ...
@@tmtoronto3741 yes it's always the one time you don't check the simulation that shit happens ha ha I will check out your latest Video Cheers Bill
Did you mill this plate with the X-50 or simply FOR the X-50?
Both, if I understand your question. I have a Woodworker X50 with 3rd rail. The plate, and completed Z axis assembly I designed, is going to replace the current stock Z20 Z axis. I am almost ready to share a video update of it - I have it installed now and almost calibrated. The Z heights are different, so I will need to reconfigure my ATC rack, but may wait until I finish initial test cuts before doing that.
@@tmtoronto3741 excellent! I should have clarified that I was asking if the video was of your X-50 making the plate or if you were using another machine to cut it.
I've got an X-35 and, while I do love it, I feel I'm nearing its limitations when it comes to cutting aluminum. I don't trust the motors to carry a spindle, and even they could provide adequate power, I worry that the rails would allow too much deflection to prove out the meaningful differences between spindle and router. So I suppose I'll just keep going slow and steady until I can afford a truly substantial machine upgrade.
@@BlackBearCustomKydex my machine never had the original motors as I installed 3Nm steppers from the start. I agree about the deflection, and although a fairly rigid and well designed machine, the Onefinity is set up more for the Makita. I will share some new deflection data in my next video showing the installation and testing of my new Z axis, but I can tell you from initial impressions that the overall design of tubes and linear bearings is now the weak point - and that will not change no matter what mods I make. I will say that my interest has now shifted to the new Altmill from Sienci. It is the kind of CNC router I would build, and it looks very capable. The first batch ships soon, and I am looking forward to real user reviews to start coming in. Check out the company videos if interested - it is not a Bridgeport, but looks like a very versatile machine for home/small business use.
So Impressive, which CAM software are you using?
Thank you for your interest and kind words. I am using the free version of Fusion for CAD and CAM.
