    cam session configuration - change from mill to lathe - possible?

    Hi guys, I have a part I was making on the 3 axis mill. Cam session configuration is of course set and all machining operations finished. I want to try making this part on the lathe. Can I use the same model and change the cam session configuration from mill to lathe and use the same model? How...

    NX cam - non linear disc milling - how?

    Hi Guys, attached is an image showing an open slot I would like to cut out with a disc mill. It is a non linear path (a couple of straight lines tangential to a curve). I can't work out how to do this, any pointers greatly appreciated... many thanks, James

    NX cam - cutting parameters, stock - Intol/Outtol

    Hi Guys, can someone kindly explain the practical use of cutting parameters settings 'Intol' and 'Outtol'. I am making some small parts on the milling machine with reasonable tolerance requirements ideally trying to hold around plus/minus 20 microns. For example I am hole milling a 4.49mm...

    Adaptive milling questions... NX1880

    Hi Guys, I am using the adaptive milling operation in NX1880. This replaces a trochoidial milling operation I was happily using. I am using high speed machining cutters (6 flute, small radial depth of cut) and coming in full axial depth of cut from the outside of the job and skimming around it...

    nx12 chamfer mill manufacturing operation - simple 0.2mm symetrical chamfer, how?

    Hi, can somebody tell me how to mill for example a 0.2mm symetrical chamfer on a 12mm hole with a 6mm, 45degree chamfer tool in nx12. I am really struggling. I am trying to use the planar mill operation and set the tracking points for my chamfer tool as I did in NX11 but the functionality...

    machining strategy - long radiused slot... - nx11 cam

    Hi Guys, attached is an image of a part I want to machine. What do you think would be the most appropriate strategy to rough and finish the radiused slot that runs along the part? cheers, Jameshttp://files.engineering.com/getfile.aspx?folder=e98b34ce-3806-483a-b70f-14d7e1fb837c&file=strategy.jpg

    slot milling with a planar milling op... -nx cam 12

    Hi Guys, I am experimenting with slot milling. I have used the very basic but sometimes useful groove milling op and the tried similar with the floor and wall op. I have a part profile I would like to make which is a bit more complicated (for me) and I believe can be accomplished with the planar...

    Peck drilling - nx11 - what, where, how!

    Hi Guys, I have a question about peck drilling in NX11. I tried to read up about this on the Siemens forum and watch some youtube videos, this all left me a little confused. One video showed NX11 being used and the primary create operation drop down has a 'drill' option, in here was a peck...

    nx11 cam - facing a blank cylinder in the milling machine.. - what op?

    Hi Guys, stupid question but I have a simple operation to perform in the milling machine and was wondering what the standard way to do it was. I have a steel disc and and want to remove 1mm off the top surface (facing op to clean it up from the saw) so it is ready for the next op on a different...

    ref thread561-404937 - laser cutting a tube, require side faces not normal to thickened sheet body

    Hi Guys, a while ago I made a post, thread561-404937 about laser cutting a tube. I now need the side faces of the cut section not normal to the thickened sheet body. Previously I was sketching the profile, wrapping it, thickening it and this was working perfectly. Now I need to change the side...

    nx cam 11 - zlevel profile with finishing pass..

    Hi Guys, sorry if this is a silly question but the zlevel profile op is very quick and easy to use. However it would be great if you could set finishing passes - I can't see how to do this. If not what is the easiest alternative or method to remove stock from an external part wall. I have been...

    nx11 cam - workpeice, specify blank, offset from part...

    Hi Guys, is there any way to offset only one side of the part? I have a symmetrical part with ground x and y edges but the edge with an arc is roughly cut in a saw. I only want to offset that side on the blank... Which leads me to the question is there any way to specify the blank using a sketch...

    nx cam 11 - how to Increase diameter of circular pocket and remove material from wall...

    Hi Guys, I have a circular pocket. I am fitting a part to it by hand. What is the easiest way to remove say for example 0.1mm material from the wall around the diameter of the pocket? I don't want to modify the model if possible (maybe this is not possible). Is there an operation or operation...

    trochoidial stock removal - how to remove stock from around the part with a trochoidial tool path?

    Hi Guys, I want to profile a piece of steel as shown in the image. You can see the blank and the final part which has a semi-circle cut from the stock perimeter. Is it possible to remove the main semi-circle of material using a trochoidial tool path and not by using the full width of the tool...

    how to add and reverse a new mcs in cam to flip part for backside machining....? - NX CAM 11

    Hi Guys, I have a part that is being machined in the vice. The part has through with large then small diameter. I would like to flip the part over so I can hole mill from the back side also. I tried to do this by adding a new mcs in the correct position and orientation (on the reverse of my...

    Nx10 cam - Do changes to your model cascade down to manufacturing?

    Hi Guys, how can I make changes in the model area of my part and have them come down into the manufacturing environment? Is this possible? For example I change the extrusion distance of a simple part from 10 to 15mm in modeling and say a hole feature but no matter what I do I can't seem to make...

    nx10 cam - object, tranform, rectangular array - program order, tool path management?

    Hi Guys, I have crated a rectangular array of parts and tool paths to machine on my vac plate. After creating the array the program order is such that nx wants to run through each tool path sequentially per part. This is of course not very efficient. I want to use the tool to cut the tool paths...

    nx10 cam, radial chamfer, how?

    Hi Guys, I would like to make an external radial chamfer on the edge of a part. So far I have been able to do an angular chamfer on the edge of a part with a planar profile operation and setting the tracking point accordingly with a chamfer tool. How do I accomplish the same thing but with an...

    nx cam - peck drilling, nx 10, example .prt file?

    Hi Guys, could someone very kindly post up a .prt file with an example of a peck drilling operation for nx10 cam? Normally I play around with the settings and then the verify operation to see what is happening but for this operation I really can't work out what is going on. I would like to run a...

    nx cam - cavity mill, change direction of tool path from clockwise to counter clockwise

    Hi Guys, first I am not sure if I am using the correct operation so let me know if there is a better way. I am facing the outside edge of a part all the way round. I am using a cavity operation with cut pattern 'follow periphery' and leave stock for a finish cut. All works but I would like to...
