Hi Joe, The blue flashing light===>> German police car hidden in the controller.... ;) Got a 4 months training on CNC lathe and machining center, that was some years ago, though, I think it was on a Fanuc controller, finally never worked with those after, I can't go without feeling the machine through the handles... And now, my shop is so small that it would be impossible to even fit even an extra grinder... Even less a machine that requires 20Kw of power to run... This presentation, take away the spinning of the camera, is a real good overview of what a CNC machine is about with all the different parameters, tool position, offsets, speeds, advance, movements, axis, etc.... Now, the younger ones ( Up to about 70 yo. ) can't ignore this to progress in the machining world... ;) Cheers, Pierre

I had the opportunity to ride a motorcycle across Belgium, Germany and the Czech republic a few years back. We were deep in the black forest of Germany and a pair of those blue flashing lights came out of nowhere, tailed us for a few miles, and vanished just as quick. Didn't see him coming and didn't see him leave. You may be right about that light. You have inspired me to fabricate a stabilizer for my GoPro camera. Its long overdue and not that complicated. Part 3 of this series is already shot, but 4 and on should be noticeably better. Always good to get a comment from you Pierre. Stay well.

Wonderful stuff Joe. You are taking the mystery out of CNCing for me. Thanks!

There are a bunch of required steps to make even the most basic part. Not knowing what they are is where all the fear comes from. I hope to lift that curtain for you guys.

Joe you could always video or still shot the V parameters as a visual backup for your machine and anyone having the same model machine to check. And also any other pages that you know the settings to be correct on if for no other reason then for your own good. Just incase for some reason those were ever changed, stranger things have been known to happen around computers. Showing Joe the love thumbs up and shared in the KZread Machinist group of over 2,300 and suggesting they likewise show Joe the love and sub.

part 3 should post tonight.

I run a Fadal 60 30 at work and thought I'd watch this series to see if I can pick up a few things that I may have missed. I started as an apprentice about 7 years ago on manual and CNC machines, am qualified now but still have lots to learn. Very informative videos. Would just like to do a quick mention that on one of the menu screens is 3-Zero return this also sends the machine back to the home position and is my preferred method. Also, when in Jog mode if you hold down the jog button the machine will travel on its own the speed is determined by the same way you would with the hand wheel and can be fine tuned via the feed rate control. Down the bottom of the screen it displays either "H" "M" or "L" (short for High (0.100) Medium (0.010) and Low(0.001)) and next to it is "+" or "-" this depicts the speed & direction it will feed which is set by the XYZ knob and the last direction the hand wheel was turned. Very handy for basic functions if you just want to face something.

Good video Joe keep them coming very interesting.

excellent teaching, really looking forward to the next lesson. Joe should do some lecturing, as he has a way of capturing your attention

All correct. Also, If you know you have a tool that starts stressing out around a certain hour mark and breaks or yields a bad part, you can be proactive and change it. If your carousel uses the same tools quite often, you can tell how old the tools are.

Great series! I'm trying to learn the basics

Hi Joe, when you were going through the tool offsets, how do you keep track of what each tool in that list (1,2,3, etc...) is? Sorry if you already mentioned that. Very informative series...please keep em coming! Thanks for sharing

@joepie221

7 жыл бұрын

Hi Neil. When you plan out a CNC job, you pretty much know what tool you will use for which feature. In the offset register, you can enter any number you want for the tool number it relates to. That tool number is a reserved space in the tool carousel and called up when the operation starts with the 'T#' prompt at the tool call block. I also record it on my setup sheet for repeat runs. Its an easy one to skip over. That would not end well. Good question.

Informative video Joe. A little different than the Fanuc controls but plenty similar. all the best from Toledo, OH Are you going to introduce your dog?

great video I don't use fixture offset 1. Offset 1 is a program default this keeps me from forgetting (to set a offset) and making a mistake.

@joepie221

E0 offset is the default for this machine. I'd be lost without E1.

Very interesting to get an inside look at how these machines work. I am a software engineer and have recently taken an interest in machine tools and machining. Looking to buy a lathe and start learning and maybe one day I will get to play with a CNC mill like this one. When was this machine built? That user interface is archaic to say the least by software engineering standards. Reminds me of a linux command line. One would think these machines would have a much more user friendly interface.

Yes, that was my question too. I'm used to seeing the machine on NYC CNC which has a touchscreen with a GUI. Same functionality from what I can tell so far. It's interesting that a 50 year old lathe or milling machine can look modern but these CNC machine "look" are archaic because of the computer technology. There's some irony in that. BTW: 4 out of 4 great videos on this channel so far.

Good show Joe. Just curious why you run your machine in Format 1.

@joepie221

7 жыл бұрын

There is a reason for it, but I just don't recall what the issue was that made it necessary. Tell me more about the format options?

At point 11:35 you mention Fixture Offsets and you explain that "these are 48 possible locations that you can identify on the work table". My understanding is that Part Zero is set by the programmer based on the blueprint for the part being made. You would use an edge finder to determine where a particular feature of the workpiece is located so the machine knows where that precise location is. Perhaps I missed something in my classes but in accordance with Tooling-U and my CNC Programming books Fixture Offsets are to tell the machine where the Part Zero is located in reference to Machine Zero so it knows where to perform the milling operations called for on the program. Is this different for Fanuc controllers?

@joepie221

7 жыл бұрын

Your understanding of the offset function is correct. The fixture offsets I speak of on this controller are open parking spaces in which you can enter any X-Y table location you desire. Where that location relates to your part is entirely up to you. I can place a fixture offset anywhere on the part, provided the part is against a stop, and still make a good part. It is an easier practice to place your zero position as driven by the baselines for the dimensions on the print. That makes for an easier visual review of the code for checks and problem solving.

Fadal is cool in this respect. Rather than G54, 55,56,57,58. Fadal said we are going to make our own values and call them "E" offsets. So you can have more than just 5 offset options. Now the cool thing is fadal will take a G54, but a Fanuc wont take an E1.

11:59 V1 through V100 are macro variables. For the Fadal machines, PDF manuals are readily available online. I got mine at flintmachine.com/fadal.php. For the user manual, I recommend renaming the files to include the page number range for each section.

Hi Joe. Great series your doing here! How accurate is the homing of the machine. If you knew the exact distance from home to the corner of your vice. Then turned it off and came back the next day. Homed it. Would that distance be the same? I only ask because I used to use Okuma's. and just switched them on the next day. And pressed the cycle button. No homing required.

@joepie221

7 жыл бұрын

The home position CS is spot on. The machine knows where its home position is and you just have to be in the area when it calibrates for the day. Never a worry from day to day. Ever. Those table reference marks are just to get in the ballpark. The machine does the rest.

The wood dowel trick is genius. Would sticks of Chalk or Glue Sticks be ok? Chalk would snap very easy, Glue stick will just bend like a cooked noodle. Pencil would be very little force to break. I am thinking just about any soft material will work as long as the tool collet can hold it. Crayons? naw thats childs play...lol

@joepie221

Anything that you can hold and break will be fine. Just stay clear of the top of the part and keep one finger on that slide hold button. I actually put a sharpie marker in the holder once and drew the part on the stock for a visual reference of the final profile. Worked for me.

Is the C-axis RPM or tool rotation?

@joepie221

Thats a good question. X is l to R, Y is in and out, Z is up and down, a and B are tilt and rotate. C???? Not so sure. S is rpm, so it must be tool rotation. ( not clockwise vs counterclockwise) small movements. best guess.

Knowing that fadal is no longer around would you buy a 4020 used? They pop up used for a decent price once in a while and seeing a detailed series on the machine may make buying one an option. What year I your machine? Thanks for sharing!
