NX CAM Resources





In this demo we show simulation inside of NX. We show the loading of a machine and give an overview of how it works inside NX, the features of it and the advantages we see in it over a third party application such as Vericut.

We use an out of the box sample file that Siemens PLM provides. It’s just the part file, no machine is loaded in the machine tool navigator. We retrieve a machine from the library and we'll choose the Hass UMC750.

Right away it tries to choose a placement point and you have a couple of options on how you want to place it. You can use a part mount junction, which is looking at the fixture and the part and mount the machine to that. You can also do it from machine zero from your MCS. If you had another machine loaded in here, you could use those old positioning constraints. But in this case, we just use the part mount junction and our machine gets loaded.

There is a known issue with NX/Post in NX release where CAM operations — for producing tool paths in terms of contact points — may not get post-processed correctly. As a result, N/C codes of certain circular motions may contain reverse direction. This problem will be fixed in Maintenance Pack 2 for NX 12.0.1 (RTM June 1, 2018).

As providers of CAM software we hear it all the time: "Where can my new guys learn NX?" We've set out to create a series of onboarding videos to get your machinist-programmer up and running in NX.

Our instructor brings an experienced but fresh eye to the material. He was introduced to NX CAM in the last five years and knows what it takes to get onboard with the program's interface and logic.

We'll add more in the series as they become available.


There’s more than one way to get somewhere in NX, so this vid covers the different methods for selection filters. Since NX defaults to selecting the body, these give you methods for selecting a face or a datum or an edge. By using selection filters, you can choose the feature you’re trying to grab. We also cover the types of visualization views available.

In this video we cover how to take measurements in NX, a necessary tool as a Programmer-Machinist. We’ll demonstrate how to use the “measure distance” dialog to measure features of your part, how to use “local radius” to measure surfaces with compound curvatures, and how to measure the distance between the cutter and the part at various points in your toolpath.

In this video we demonstrate how to use assembly constraints in CAM files. Assembly constraints are used to quickly position the components in your files and more importantly they define the relationships between the components in your files. Using assembly constraints helps ensure that your machine setup in NX will match the real-life machine setup on the shop floor, making it easier to identify and prevent any issues that may develop at run-time.

If you’re running into problems with your 3-axis toolpaths, check out this 30 minute session to learn about the Tilt Tool Axis method. We’ve seen good results in using this command to fix and avoid tool holder collisions.

We looked at this method in older versions, and we’re pleased to say it’s made a solid leap forward in its effectiveness in NX 11. Using this method, NX either trims the tool path and retracts the tool, or replaces the 3-axis, 4-axis, or 5-axis motions with 5-axis tilting motions that are extremely smooth.

With this command, you can:

  • Reach greater depths using the shortest tools possible for added rigidity
  • Adjust the tool path for fixed-axis, 4-axis, and 5-axis operations
  • Use tools without a defined shank or holder
  • Use ball or non-ball tools
  • Modify the tool tilt multiple times in direct succession
