Creo Parametric Mil -Turn 3/128 Table of contents Creo Parametric Mil -Turn 4/128 Creo Parametric Mil -Turn 5/128 CREO PARAMETRIC INTERFACE 1.1This book This book is a follow-up to the books Creo Parametric Modeling, Creo Paramet-ric Basic Milling and Creo Parametric Basic Turning. If you already know the basis of the Creo Parametric and modeling you can use this book easily. If you are using the software first time, and want to go straight to the CAM module, you can download the needed 3D models and tools: The downloaded models are in the native Creo Parametric 2-format (.prt), (.asm), (.drw) and (mfg). The models are also available in the STEP-format.

Before you use Creo Parametric to machine components (CAM), it is important to understand the complete manufacturing process and the steps involved in this pro cess. It is also important to understand the elements that make up completed manu facturing models. Download site: http://www.gold-cam.fi/en/download Or inquire 1.2

Using template manufacturing models enables you to standardize on the initial manufacturing model configuration. By default, the template manufactur ing model includes default datum planes and a default coordinate system. The reference model represents the final machined component. The reference model represents the final machined component.

Surfaces and edges are selected from the reference model and are used as references when cre ating NC steps. The reference model can be also imported from the other CAD software. You must assemble a reference model before creating NC steps. 3. Workpiece model This represents the unmachined stock material. It is an op tional element and is not required to create NC steps.

However, using a workpiece enables you to simulate the machining of the stock material. Workpieces can be standard stock billets or you can configure them to represent models such as castings. 4. You can assemble or create a workpiece in a manufacturing model. A number of options are available. 5. Fixtures are parts or assemblies that can be used to hold the component being machined. Fixtures are parts or assemblies that can be used to hold the component being machined.

For example, you can create chuck assemblies and use them as fix tures. 6. An NC sequence is a workpiece feature that represents a single tool path. The tool path consists of: Cut motions, that is, tool motions while actually cutting the workpiece material Approach, exit, connect moves Additional CL commands and post-processor words (for example, feedrates, PPRINT, OPSTOP). 7. Toolpaths and machine simulations are one of the most important stages in the manufacturing process.

You can display the toolpath for an operation, a single step, or multiple steps. You can also display tool path and machine simulation to gether if the machine assembly is defined. 8. Post-processing is the final stage in the manufacturing process. When toolpaths and simulation have been completed, you can create ASCII format cutter location (CL) data files for operations or selected NC steps.
