Looks good from what I can see... go ahead man...lol

Just a suggestion on how you can do that. I use a param in the begining of program where I store the workoffset#, and keep recall it If u use more then 2 wpc on your prg things gets a bit complicated but u can do it(use buffers) . This way your guys can change on the fly what workoffset# they want to use, and you won't need to change ur MC file Fanuc: G20(INCH PROGRAM) #531=58.(WPC USED) G90G10L2P0X0Y0Z0W0B0 G90G10L2P5X-40.1815Y-22.0008Z-47.086W-5.B359.995 G59G90G40G80G98G17 M301(RETRACT FOR TOOL CHANGE) M01 (--------------------) N4T4(2" INS EM R0.06 FIN TC=6) M6(MAX=Z5.

So gents... ..in the end can someone layout in very specific way and with details, how this guy can achieve that 0.001 true position using probing cycles? I'm asking because I'd like to learn also how. Or he should buy camplete cuz that software has a miraculous function on how to achieve that tolerance. Thanks guys

This is so funny..lol Why you guys even bother bringing arguments pro-fanuc or pro-Sinumerik. It's well known that Sinumerik is the most powerful controller out there.

Just a question. What's the value you have on angle increment in tool axis control?

This new file has all the rads from that model finished....didn't have time to finish all on the 1st file I attached ...busy here....lol ajmer_ihs_CORNER RADIUS.mcam

How about a simpler solution? I will finish the walls and floors til where the rad starts then do the rads like in the example attached. I would also add some multipass cuts to just remove the most of material on those rads 1st leaving let's say 0.01, then a finish cut like in the file. You can have comp on the cutter and control the size also and plus less code. See attachment ajmer_ihs_CORNER RADIUS.mcam

+1 Sinumerik is a different animal. If a manufacturer configure his machine well, with all what Sinumerik can do, it blows out any controller out there in any application. Fanuc is reliable mostly cuz ..let's say..his "simplicity" and from here is easier to handle by a manufacturer. But is growing,.. and the more will grow, the more difficult to handle will be.

Well...sometimes you can. ..this a proven program from last week.

Yep...same problem here. I think the new Tool change option from Safety Zone is causing the issue. There is no option to not have this option disabled somehow. It will "feed" a tool change regardless of what option from those 3 you choose. Post must be changed. I just temporary disabled the switch in my post who was causing the retraction, then post my tool path. I didn't have time to look into it, 'cause different scenarios...and no time... Anybody else looked more into that?

I'm using in machine for a inch file like in this example and same result (I uploaded the file just above).. So won't help..sorry. About features being cut oversize...well.. sometime no....it will gauge. Let me elaborate and show you what it can happen: Sinumerik controller: T1 M6 G54 D1 G90 G0 X-.754 Y4.1 Z.1 Z0 N5 G1 G41 X-.9367 N6 G3 X-.9368 Y4.1 Z-.445 I.1827 J0. TURN=22 N7 X-.5713 Y4.1 Z-.455 I.1827 J0. N8 X-.5713 Y4.1 I-.1827 J0. N9 G1 G40 X-.754 N10 G0 Z1. N12 M30 In this situation a gouge can occur. When? Let's say the operator has to interpolate a fine bore and he's putting a 0.005 or 0.01 in tool data in the controller to check what size he'll get, and compensate after. Since the starting pos in G1 line and the end of arc abs position are different, the controller will interpolate like in the pics I posted. If those points r identical, then there is no problem for him to keep adjusting the cutter size. Even if there is no comp in tool data the actual tool movement won't be a truly cylindrical one, but very close. If you keep changing the Xpos of the point in the G1 line(you can increase or decrease the value as per 2nd pic) and simulate in cimco and look from front plane (Siemens 840D adv) you will see the difference. So if the points match=>no issue. If the points differ=>issues. This is from experience playing at the controller. I know that some can advice to do all kind of things to avoid this problem, but again is not about that. It's about getting spotless code up to the last 0.0001 from a CAM system, and that's were I'm pointing now. Again, if someone can point me in the direction to achieve no variation in X Y I or J using that file uploaded then will be great, and my problem will be solved. Thanks a lot. Arc.mcx-9

Thanks Ron for taking your time looking into this. All In-House 5x posts and default ones (at least mine) have same issue, and when your have a machine where you want your arcs 360deg is even worse cuz you can get errors like the one I pointed b4: N5 G41 X-.9367 N6 G3 X-.9368 Y4.1 Z-.445 I.1827 J0. TURN=22 Keep changing the tolerance around between planes 2get good output is not a valid solution, I think we all agree 2 that. As for your solution, I know is just a temporary fix...what you are doing when you forget about that or you don't check your code?... And of course there are other solutions (changing cutter size..etc etc.). What I'm looking for is 2 solve the problem at it's core, and the issue to be addressed and fixed (unless someone is finding that I'm doing something wrong....I wish that, cuz the problem will be solved...lol). So maybe someone from In-House can look into that pls. Btw: did your 5x post from Postability gives you a good code for both planes/operations? Thx

You are using a different MD (a 4axis one). Use a 5axis MD, and post same file pls..and you wont get same results even with those settings you pointed b4 I used a default one (check my file)

Sorry JP, but you're wrong. I'm worry about it and for 2 reasons: 1. Code should be spotless up to the last 0.0001 regarding on situation. You cannot just sweep a problem under the carpet. 2. On some controllers because this type of rounding you can scrap the part. I'm always check my Sinumerik post for this type of errors N5 G41 X-.9367 N6 G3 X-.9368 Y4.1 Z-.445 I.1827 J0.

That did it guys. Thanks. But I still have a smaaaaaal (it's just 0.0001..lol..) problem ... See attached mcx file. Same I and J..... Arc.mcx-9

I know..that's why I said I,J, and X. ...and it's not fine at all. The code should be consistent regardless of situation, and it is not. Any suggestion?

Using X9, Mpmaster, operation type Helix bore (see attached mcx file) I'm getting different values on I J and (in this case) X, when the tool is doing last pass at final depth.

Anyone know why and can advice please? PS: It's not about a workaround to this specific example (like changing tool size so its rad will get rounded at a 4th decimal or something else). I'm more into, why it this happen and how it can be fixed please. Thanks Arc.mcx-9
