To make things easier, (on Haas controls) rather than copying/pasting the profile cutting for successive passes at further z depths, you could use M97, and put the repeated code after M30, that way, if you need to change any of this code, you do it once. And your program looks cleaner/shorter.

do you mean that the incremental distance is relative to the center point of the arc, or the point where the horizontal and vertical lines that go through the start point and end intersect..in this case they are the same..but if the arc were say less than a 90 degree arc..what then? thanks

After "G01 Y-1.50" the mill is positioned to the right. Then for the G03, it must be tangent to the arc. The mill must be a radius down, and a diameter to the left. And, then it follows the arc, plus the comp offset. What moved the mill from G01 end to the G03 beginning? That algorithm must be pretty interesting, since it has to know a lot about the previous function and the next function.

R seems faster but IJ is pretty universal. Some machines keep you on your toes using L or what have you. Our fanuc edm apparently can take R but can't, was told to change all posts to R for easier editing and found out the fun way. Did I miss something or was this assumed that you'd add the tool radius in on the machine to get the part in spec? Without this its incorrect.

Mark climb milling/cutting is used to assist the machine. It's easier on the machine as it pulls the material through with the rotation of the cutter you're using.

For what control is he programming for I would never put the cutter comp and tool offset on he same value 01 on most controls that would mean a nice scrap part or just ALARM out for D value rule of thumb add 50 so that means D should be G41 D51
@YokumFireworks1
7 жыл бұрын
D stands for Diameter offset and the 1 correlates what the tool number is. This is used in most fanuk controls and you would make it .51 in the offset page on the tool 5 slot not at the D value in the program itself.

For the straight cuts, how come you are only using an X or Y value to move to the next point? Doesn't the tool always reference from the origin? So wouldn't writing the actual coordinates (X & Y) make more sense? Otherwise using Y or X by themselves would be moving relative to origin, not to the next point in cut path.
@eipylOh
9 жыл бұрын
forr3st125 I wondered this too. If no Y is given it would surely return to 0 on the Y whilst moving to the given X coordinate given the machine is set to absolute.. unless the machine takes the last known Y coordinate?
@billykorevec535

you only have to use one x or y if the previous value is the same because the numbers remain modal like G01
@farmzoid1899

You have an error in the program. Before your first G03 move you will have to make a G02 move to roll the cutter around the point 90 degrees CW. Then invoke the G03 move. You will then have to make another 90 degree G02 to roll the cutter around the point, then use the G01 move. Another fix would be to continue the G01 command in the -Y direction 1/2 the cutter diameter, then invoke the G03 command. This does not keep the cutter in constant contact with part and could effect your finish.
@bogart-fv5wi

Farmzoid, not necessarily so, it will depend on how you use cutter compensation. ie. center line of tool programming vs. tool edge programming. In the video example the teacher is using center of tool, so at the machine you will need to put in the tool radius on comps

He did not explain clearly that he was programming to follow the lines using a theoretical zero diameter tool. Then all you have to do is put half the diameter of the tool in the diameter offset table. So with a .500 endmill he would put .25 in offset # 1 and cutter compensation would take care of it. I believe you thought he was programming the center of a .500 endmill, in which case your observations are perfectly correct. He did in fact explain that he was using cutter comp (G41) but he could have been clearer This subject does take a while to wrap your brain around.

we prefer to climb mill on CNC's because it leaves a better finish, climb milling is not a requirement. On conventional mills we have to always conventional mill because a climb mill on a Bridgeport will grab the material, suck up the backlash and potentially crash the cutter. CNC's do not do this because they have ball screws with zero backlash. A CNC with acme screws would have the same problem, a conventional mill would be able to climb mill if it had ball screws.

Learn how to be a teacher without telling everyone how to do it wrong then have to go back and correct yourself. I have watched about 10 video on I and J interpolation and every one of them has made mistakes which I have to go back and unlearn what they just said so I can go back to learn how to do it correctly. As soon as I finally understand the I and J positions, I will make a video of my own that people can understand.

Ridiculously complicated. Just for a rounded corner. And inches. The old imperial system. Madness. Climb milling? Why is it called CLIMB milling?
@bigjame26
9 жыл бұрын
mardrom1 Climb milling is just a way to explain, in most cases, the rotation of the cutting tool (in this case an endmill) in relation to the edge of the work piece. climb milling "pulls" at the workpiece and conventional milling "scoops" out the chips. because of backlash in conventional mill machines, climb milling is only ever done for a finish pass, about a thousandth or two. however, cnc machines dont have this backlash issue and primarily are run using the climb mill technique. check this out: img39.photobucket.com/albums/v119/vinnito/storage/cmill.jpg

There are aternative methods for circular interpolation. For example, you can avoid the I & J, and add in a radius R. Just make sure your machine control parameters are setting allow it. For the 1st arc, program this instead: G01X2.75Y0 G02X3.0Y-.25R.25 Or you can also simply program the first corner like this; G01X3.0Y0,R.25 Change the R with C if you want a 45 degree chamfer instead. This will technique will only work on corners. The term "climb" is used because the tool's cutting flute enters the stock where the chip will generally be thicker. As the flute rotates through the material, the chip will thin out. The resulting forced will push the tool away from the stock, and also forward as though the tool is climbing along the material edge. Think of an ice cliff "climber" using ice axes to chop into the ice and pull themselves up. The metric system is obviously easier to use, but unfortunately in the USA, the imperial system is still very popular. The switch is ongoing, but will take more time.

Mark Szakos G01X3.0Y0,R.25 certainly simplifies things. with the addition of changing R to C for a Chanfer is also appreciated. Your analogy to rock climbing with climb milling is easy to understand. Thank you. As for the Imperial system, well i hope we will see less and less of this, as older generations go into retirement. We are of course stuck with screw threads. Nothing can be done there. People keep on telling me simple is always best. Thanks for the easily digestible answers. Helpful.
