Applying these concepts, prior to creating operations, will save you considerable time in the creation of your program. Objectives Upon completion of this lesson, you will be able to: • Know the six steps of the NC Programming Sequence • Recognize and identify the five different Manufacturing toolbars • Understand the NX Manufacturing Process • Select the CAM Express Role and create the Manufacturing Setup • Recognize and identify the differences in creating program, tool, geometry and method parent group objects • Recognize and identify the usage differences in operations • Understand the meaning of generating a tool path • Recognize and use the Operation Navigator ©UGS Corp., All Rights Reserved NX Manufacturing Fundamentals 1-1 Basic CAM Fundamentals 1 The NC Programming Sequence The normal sequence of steps, in the NC Programming Sequence of the NX Manufacturing Application, is to perform the following: • Create the Manufacturing Setup - creates a manufacturing assembly and adds other data related to your type of part. • Establish the Parent Group objects - minimizes the selection of objects for repeated use and establishes the concept of inheritance, where parameters can be passed down to other objects. • Create the operation(s) - allows you to assign specific parameters and methods that affect how the tool path is created. • Verify the tool paths created - minimizes errors by visualization of the tool path. • Post Process the tool paths - formats the data for your particular machine tool/controller combination. • Create Shop Documentation - minimizes the effort that shop personnel uses to set up and process the individual job. This sequence is shown in the following Manufacturing Process flow chart. 1-2 NX Manufacturing Fundamentals ©UGS Corp., All Rights Reserved mt11021_s NX 5 Basic CAM Fundamentals 1 ©UGS Corp., All Rights Reserved NX Manufacturing Fundamentals 1-3 Basic CAM Fundamentals 1 Manufacturing toolbars Five toolbars exist for the Manufacturing application. They are: 1-4 • Manufacturing Create - allows the creation of operations and groups (program, tool, geometry and method) in your NC program. The four group creation dialogs allows for the creation of groups that define parameters shared among operations. The position of any group may be changed by cutting and pasting above, below, or inside of any other group in the Operation Navigator. • Manufacturing Operations - allows the selection of functions related to the generation and verification of tool paths as well as post processing and the creation of shop documentation. • Manufacturing Objects - allows for editing, cutting, copying, pasting, deletion and displaying of an object. • Manufacturing Workpiece - allows for displaying and saving of a 2D and 3D work piece object.

The Operation Navigator allows you to specify groups of parameters that are shared among operations. The Operation Navigator allows you to view objects in the Program Order, Machine Tool, Geometry or Method view, using a tree structure to illustrate the relationships between groups and operations. Parameters may be passed down or inherited from group to group and from group to operation based on the positional relationships in the Operation Navigator. ©UGS Corp., All Rights Reserved NX Manufacturing Fundamentals 1-5 1 Basic CAM Fundamentals 1 Create the Manufacturing assembly In Manufacturing, Assemblies pertain to the Master Model conceptThis concept protects the design criteria from corruption by other users. When you create a Manufacturing Assembly and add a component, such as a fixture plate or clamping device, application specific data can be generated in a separate part file that will reference the master geometry. This prevents the duplication of model geometry and allows for the concurrent use of the Master Model. 1-6 NX Manufacturing Fundamentals ©UGS Corp., All Rights Reserved mt11021_s NX 5 Basic CAM Fundamentals 1 Creating the Manufacturing Setup When using CAM Express templates, the Manufacturing Setup creates a master model assembly where the setup part is the top level assembly. This allows the Programs, Tools, Geometry and Machining Method groups to be created in a separate file than the master model. This is normally the parent of the Manufacturing Assembly. The Manufacturing Setup also includes Manufacturing Templates that are most likely to be used on a specific part type. Setup Templates include the following for inch and metric parts; • DieMold Express • Turning Express • Machinery Express • Multi Axis Express These templates create some basic parent groups for you. These include: • A Program group. • A tool Carrier and 30 Pockets • An MCS parent group with an empty Geometry group. • Method groups The templates also load creation templates for the four parent groups. The templates will match the part type that you selected when you created the Setup ©UGS Corp., All Rights Reserved NX Manufacturing Fundamentals 1-7 Basic CAM Fundamentals 1 Create an Operation Before you create an operation, you may assign the: Program Geometry Tool and Method Parent Group to the operation. First you select the operation type (Subtype), then the various Parent Group objects and then finally the Name of the operation. Note that if you select the Subtype after the Name, the Name is changed to the default of the Subtype 1-8 NX Manufacturing Fundamentals ©UGS Corp., All Rights Reserved mt11021_s NX 5
