This 20-minute Tech Tip webinar shows how to create a manufacturing setup in NX CAM.
Tech Tip by Phil Malcove, Siemens PLM Software
A proper manufacturing setup can save lots of time and effort at the machine tool - and they're simple to create.
These are some of the benefits that you can expect:

This question was asked during the live Tech Tip webcast:Q: Did you build the Reuse Library shown in this Tech Tip? Or is it out-of-the-box?A: The Reuse Library is a general capability to create and use common components. The library content in this session were primarily constructed by our technical sales team for demo purposes.
This question was asked during the live Tech Tip webcast:Q: How does NX compare to Mastercam's Dynamic Milling and rapid material removal?A: The NX CAM trochoidal roughing patterns, though not completely the same, have comparable material removal rates. Feed rates remain high and stepovers remain consistent for optimized tool usage.There is also an available plug-in for NX CAM from our partner, Celeritive (www.celeritive.com), called VoluMill(tm)
This question was asked during the live Tech Tip webcast:Q: Was that a generic NX shop doc or is that one you have customized?A: The Shop Documentation format shown is provided as a standard template in NX. It is also possible to customize the shop doc templates using Microsoft Excel.
This question was asked during the live Tech Tip webcast:Q: Is the pencil trace with flow cut a die-mold package function?A: Yes. The Flow Cut operation type in NX covers several valley restmilling cases, including pencil traces. It is included along with other 3 axis surface milling content in our standard packaging.
This question was asked during the live Tech Tip webcast:Q: When using linked body, there are two cases when replacing component:
new component is derived from same part as original and
new component not derived from same part.
What are the considerations as far as having to reselect geometry to define workpiece geometry?A: In either case, the tool paths can be associatively updated to the new geometry. There are options available to “map” existing selections to a new component as described in part (2) of your question. In either case, any new geometry that did not exist on the original design will have to be selected as needed for each operation.
This question was asked during the live Tech Tip webcast:Q: Is there a way to learn NX CAD/CAM at home? A: In addition to the regular documentation, there are nine in-software tutorials which make a good starting point for learning the system. Look under the Help menu to get started on the tutorials.Many more tutorials and examples are included in the NX Learning Advantage on-line training, available to subscribers:Catalog: http://training.industrysoftware.automation.siemens.com/mytraining/sp_list.cfm Membership types: http://training.industrysoftware.automation.siemens.com/mytraining/memberships.cfmYou can also attend instruct-led classes:Catalog: http://training.industrysoftware.automation.siemens.com/courses/ilt_list.cfmCheck availability (US, Canada): http://training.industrysoftware.automation.siemens.com/courses/finder.cfm
This question was asked during the live Tech Tip webcast:Q: I am new to NX… how hard is making the templates? I have never built a template before. Is there a good tutorial available for that?A: NC Setup Templates are just part files, saved and indexed as templates. It is not hard to create additional templates, customized to your best practices. Additionally, NC objects such as operations and geometry groups can be stored in part files and used as templates. This flexibility in template creation makes it possible to fine tune your NX installation to match your work flow.You can read about template creation in the NX documentation, in the CAM Customization section.There is a CAM Customization course available also. It can be attended live, or found in the Learning Center courses online.
This question was asked during the live Tech Tip webcast:Q: Does the machine simulation model require a secondary NX license?A: There is a software license required to create machine simulation models and/or use these models to simulation NC motion. It is included in most product packages, and available as an add-on for any packages that do not include it. A CAD license is required to build up machine models from scratch.
This question was asked during the live Tech Tip webcast:Q: Do you have a library of machine models for simulation?A: Yes. In your software install: …\NXn\Mach\resource\library\machine\installed_machines
This question was asked during the live Tech Tip webcast:Q1: Is it possible to use an expression value as a parameter in NX manufacturing menu fields?A1: Yes. NX CAM will resolve expressions on the flyQ2: Does the parameter stay associative when the value is changed?A2: Not in most cases. Unlike the CAD application, the CAM application does not store an expression as the input for a parameter field. It instead resolves the expression and stores the resultant value.
This question was asked during the live Tech Tip webcast:Q: How do you cover up holes and slots again?A: There are several tools available on the “Geometry” toolbar (sometimes referred to as the Model Edit toolbar) in the CAM application. Some are explicitly “patch” tools. Others are Synchronous Modeling tools, such as face delete. The “Geometry” toolbar, found at the bottom of the screen. If it isn’t visible, turn it on using RMB on the grey toolbar area and turn it on.
This question was asked during the live Tech Tip webcast:Q: Where is the best place to learn how to set-up the materials and feeds and speeds tables?A: The best place to get started is with the software documentation, under Manufacturing/General/CAM Libraries/Machining Data Libraries. A few pointers:
In order to use the out-of-the-box (OOTB) data, make sure that your tool material, part material, and cut methods match up with the machining database types. These are all prefixed with “HSM_.”
The UI for editing or adding data is found under the Tools menu: Tools/Edit Machining Data Libraries
If you have some spreadsheet data to import, you can use the sample Excel file to format it for import into the machining data library: ..\MACH\resource\libraries\feeds_speeds\ascii\sample machining data.csv
The easiest way to start manipulating the data for your own purposes is to first get rid of unused data, for example tool materials that you don’t use. Then just add data for whatever works well. The system interpolates data from its entries, so the more good base data it has, the better the interpolated results.
