My First G-code/CNC

[toddalin]

This shows a billet aluminum spacer that I devised for an alternator bracket that I invented. I have a guy turn these out for me on a Fadal 4020.

The photos also show one that I did out of a 2"x4" on my ShopMaster that I programmed using the G-simple software with the G-code slightly modified in Notepad.

Takes him about 12 minutes to make one and takes me about 10 times that long and I didn't even add the slots and hole.

The code. I edit it in Notepad.

I'm curious as to how the feed rate of 3.937 came about. Did the software come up with that?

...and takes me about 10 times that long]

Spindle speed seems a bit slow, assuming that you are working with aluminum...or wood. (but I have no idea what your max speed is)

Higher spindle speed means faster feed, which means less time to make the part. An aluminum specific three flute end mill is a good thing.

Thanks.

I told the program that it was 1.2 Case carburizing steel which was the only material listed for that tool in their library. G-simple includes aluminum, but not wood. I used a 3/8" endmill. Their sample library 3/8" tool, that I used for the simulation, is not intended for aluminum so IIRC, it balks at that combination.

Spindle speed, feed rates, and plunge and cutting depths are based on the software for that tool in that material. I actually increased the cutting depth of each cut from 0.07 something" to 0.1" to save code.

In actuality, my machine does not recognize spindle speed and I have to change the pullies to change this, so that code is ignored as are such things as tool changes and coolant toggle.

I didn't look at your entire program, but I see a lot of wasted Z moves and you shouldn't have to define a feed rate at every move, Once you set a feed rate, it should stay at that until you tell it to do something else.

At 1000 RPM, I would have used something like 10 IPM feed rate. I know at 3,000 RPM, I will use 20 to 30 IPM, and that's for the finish cut. For ruffing, I'll use 4,500 RPM and feed rate of 30 to 45 IPM.

[GlennW]

Just to clarify, feed rate is a function of the type of material being cut, spindle rpm, cutter diameter, type of cutter, and number of flutes.

It's not a set value in relation to just rpm.

[Mid Day Machining]

The code. I edit it in Notepad.

If you'll send me the dimensions of your part, type of machine and control, and the tools you want to use, I'll make you a program in GibbsCam. There is no way that part should take you 10 times as long to run it on your machine as it does on a FADAL. 4 or 5 times, maybe, but not 10. I also will need to know if your machine requires line numbers. I leave those out just to shorten the program size. If you don't need line numbers, that's over 1300 characters you don't need to type in.

Your G commands are modal, meaning if you tell it G0/G00 it will stay in G0/G00 until you tell it something else like G1/G01. Then it will stay in G1/G01 until you tell it something else. Your feed rate should only have to be given one time, not on every line.

Your G-Simple program looks to be causing more problems that it cures. I can help.

BOO-HISS...the G-word.

For those that have never cut wood, the feedrate is also a function of the direction of cut RELATIVE to the direction of grain....if you want a good looking part at the end of the day.

I have a couple of cabinet maker-customers in Sweden, and one thing they do there besides cut Titanium is whack a lot of wood.

I recognize that there is a lot of redundancy and wasted code, but the simplicity of the G-simple program trumps all of that and I can always go back and edit the code.

To make the code you see, once I got everything figured out (e.g., how to assign the tools and tool holder etc. which took most of the time), all I had to input was the end points and radius for the three arcs (i.e., the 1.125" diameter half circle and the two 0.5" diameter quarter circles), and endpoints for the three straight lines that connect them, and the program did the rest.

Once I basically knew what I was doing, it took just a few minutes to generate all that code you see without the use of a CAD program.

[Bill Shields]

Huh?

Maybe you are missing the concept of MODALITY.

[toddalin]

Huh?

Maybe you are missing the concept of MODALITY.

I fully understand the concept.

As I said, the code is produced by the software and certainly I could remove the redundancy if I needed to save space. But it would take me more time to go through and remove it than it would add to the run-time and this was only a "lesson." I just wanted to see if I could do it.

The guy makes them much faster on the Fadal because he uses aluminum with a faster feed rate and bigger cuts. I specified steel for the simulation, but can always modify the feed rates. Besides, at $12-15 each for parts and labor, I couldn't compete with that.

BTW, if someone thinks that they can undercut that price, I'm all ears!





BTW, if I'm cutting wood and my machine has a maximum speed of 2,500 RPM, is that the speed I should be using?

[Bill Shields]

if you move the decimal point over one place for wood and carbide tools, you are getting close to what commercial machines use.

if 2500 is all you have, go with it.
