Hey Joe, Welcome back and great video. One suggestion for the last operation. Instead of pecking the counter bore with a 3/8 cutter. Go back in with the 5/16 and helical ramp to final z depth. You will not have bird nesting and no worries on marring the finished surfaces. Saves on tooling cost and set up as well. Win-Win.

Hey Joe, love the series. I appreciate when an experienced hand shows a method I have not previously experienced (such as the arbor for boring a stack of shims!). A couple of observations based on my loooong learning curve making thousands of the same few aluminum parts on a 1991 Haas VF3 (approximately the same spindle speed and IPM limitations you probably deal with). 1. Try using a stub parabolic for short holes like the "half hole". No center drill, no peck, and feeds in the 30-40 ipm range make short work and no tool changes. Especially good for jobs with lots of tapping, and I have become a form tap convert for almost all jobs. I can get over 1000 accurate 1/4-20 tapped holes in 6061 before I even need to START worrying about the drill. Prices on parabolics have also become quite reasonable with more manufacturers making them. 2. It looked like you used G98 for your canned cycles on the first op (i.e. G83 G98 R.1 Z-.5 Q.15 F18.), but may have forgotten on the third. I know, I know, I'm nitpicking, but it's always a time saver when you can eliminate that hop between R levels at the start of the cycle with multiple fixtures. 3. Have you tried tiny pecks (like .010-.015) and aggressive feed (40-50 ipm) in G73 to eliminate the rat's nest and maintain cosmetic surface finish when counterboring? This is also where the 3 Flute EMs that some guys are harping on can boost your feed rates. Since they are basically purpose-designed for aluminum, the coatings and chip breaking/evacuation are optimized for this type of work. Looking forward to more great vids!

I don't know what the RPM limitations are on that particular machine but a Fraisa AXFP 1/2" or 3/8" 3 flute rougher you could run your 3 pass roughing in a single depth cut profile 1 time around the part at 30% higher feed (3 flute) saving you 2 passes on 2 parts per cycle and in Aluminum they last forever, I've been using a 1/2" AXFP for 2 years and its still fine. Still plenty of time to band saw out the chunks. That's a great tip btw. Its nice that you're doing something during the cycle and the cycle time is shorter. More parts in less time. Standard operation at our shop as well.

Interesting. I've never had much success using cutter compensation to generate a tool path from the part outline. The control would get confused at times and shoot off in odd directions. When I looked at the math I realized that it requires multiple lines of g code to figure out what direction to offset the cutter. As far as work holding goes, this part is a poster child for superglue to a fixture plate. NYCCNC has done a ton of videos on that. If I could get away with it, I'd use holding tabs and probably clamp the stock directly to the table with some sacrificial material under it. The only problem with that occurs if you need to flip the part and do 2nd side ops. It's very hard to get correct alignment after the flip unless you drill a through hole as a position reference, machine the rough stock to exact width, or touch off on the front edge after the flip instead of the fixed jaw. Beautiful finish on that part.
@joepie2215 жыл бұрын
Super glue can let go under heat and pressure and is not very efficient of a production run. One piece its OK, but for dozens, the cleanup between parts is just not cost effective.

Joe, you should look into the Witte Vacmat system or similar products. I run brackets and parts like this out of aluminum plate all the time, leaving 0.2mm of the plate so the cutter doesn't go all the way through. Out of the machine comes 20-30 parts that are connected by thin foil that you just break apart by hand. Subsequent operations I do much like you do with soft jaws etc.

Again and interesting video. The one thing that would concern me is when you are cutting out the blank you are running the mill and the bandsaw at the same time. The problem is that in a production type mode I would not allow someone to have their fingers this close to the blade. A piece of 3/4 pine notched out removes the fingers from the immediate area. I'm not sure that the amount of time running back and forth and the actual time that it would take to cut all the parts at once would be that great. I like to focus on one operation at a time when my fingers are involved. You only get one set. Nice video. Charles, Boston

Taking a chamfer cut around the perimeter before you finish mill the perimeter & the face will ensure that you don’t have a micro-burr that effects the dimensions since any micro-burr would be along the 45 degree angled face of the chamfer.

Have you heard of the superglue and masking tape trick? John from NYCCNC really likes it and it allows him to machine a part from all sides, without anny grip stock. Also, it would propably be a good idea to have multiple setups in the same machine. One for the front side, one for the backside and one for the holes. Machine everything in one program and then just shuffle the parts to the next station, with one new stock piece in and one finished part out.

I use this method frequently ,but use talon grip jaws for the 1st op. You can get pretty aggressive holding in talon grips. The only downside is barstock with rounded edges doesn't work so well. But since a majority of my mill work is aluminum or plastic I saw my blanks from plate on a tablesaw which I believe is a greatly overlooked tool for a machine shop. With the right blade aluminum cuts as easy as wood.

How do you like your Talons overall? Is the accessory and overhead cost worthwhile? I'm debating selling a version of a rough stock holding jaw I developed for myself. Cheap inserts, about 0.014" of bite per jaw so even gripping saw cuts or uneven stock is no problem. I've been using them in a 4 axis machine and running some pretty big drills from the sides. The only comparable jaws I've seen have extremely expensive inserts, whereas mine are pennies and available everywhere (not a great profit strategy).

I'm sure you could but why? You would still have those large chunks of material that -could- probably will get jammed up when they come free and break your tool. Besides it gives you something to do while other parts are running. If its a big deal just machine those areas completely away on the fist op, that's what I normally do anyway so you don't have to worry or mess with it. Especially in aluminum when it takes very lil time to plow through it, also makes it easier to use a trochoidal tool path rather than slotting when you do.

Yes, a hard stop is locating the parts the same each time.

Already few years old video, so hopefully still read. My question is, if you didn`t have bandsaw, how would have you done the second operation to get rid of the excess stock? Facemill I`m afraid would end up catastrophe when the stock lift up and jam between the stock and mill? Maybe endmill strictly follow the path of the clamp. Then once the excessive stock is cut loose, have optional stop and take the stock out and continue program? Or something else? Thanks.

On second operations, you always risk big chunks getting sucked up into the cutter. And, solid material is more valuable as scrap and misc pieces for jigs than chips. Thats why I cut on the bandsaw between parts. Plus a bandsaw is quicker if the CNC machine is already running. If you are leary about the corners or islands jamming the cutters, do a quick profile pass first on the second side op. Maybe you can use coolant pressure and direction to control where those chunks go. To be 100% safe, include an M1 in your code and blow them out of the way.

How do you set you’re peck drilling parameters? While watching this video i noticed a lot of up and down travel and was wondering about saving time on cnc operations by fine tuning this feature.

This was a very cosmetic part and long drill chips whipping around was not preferred. The operation was either a deep hole, or peck cycle. My machine offers 3 choices. Drill is just straight through, peck is interrupted, and deep hole pulls the drill out of the hole all the way between pecks. My controller gives me complete control over the speed, feed rate, peck depth. My settings vary based on hole size, material and finish required.

WOW, Not banging the stock in the vise before the first pass makes so much sense now! What is the preferred Grip Stock thickness you shoot for? I tried a similar approach to this earlier today on a set of parallel jaws, after watching your video on squaring stock. I left a 7”x3/4”x1/4” grip stock flat that I’ll finish decking the bottom off tomorrow, but I think I could’ve gotten away with 1/8” grip stock since the parts span the whole 6” Kurt vise jaw(s). Also when torquing the vice, what torque value would you suggest for Aluminum? Thanks again for the great content, I feel like Descartes standing on the shoulders of a giant when I watch your channel!
