Prismatic Machining Preparation Assistant in a Nutshell Prismatic Machining Preparation Assistant delivers Machinable Features recognition and associated functionalities for preparing a design part for Prismatic Machining. This product assists the NC programmer in making the link between Design and Manufacturing. It provides a set of functionalities that generate all Prismatic Machinable Features of the design part. It builds a real Manufacturing View of the design part with all the drilling and milling features to be machined. Thanks to its Machinable Features Recognition technology, Prismatic Machining Preparation Assistant allows Prismatic Machinable Features creation for all kinds of CATIA Version 5 design parts, including those with no Design Feature specifications, as well as non-CATIA Version 5 design parts. It is totally integrated with the Prismatic Machining and Advanced Machining products. It dramatically reduces programming times by automatically creating all geometric areas that must be machined with Prismatic Machining operations, reducing time spent in geometry selections. All Machinable Features can be fully machined with Prismatic Machining strategies by creating elementary machining operations or applying more complex machining processes in both drilling and milling domains. Prismatic Machining Preparation Assistant offers the following main capabilities: G Automatically creates all Prismatic Machinable Features of a design part G Locally creates a Prismatic Machining Feature of a design part G Machinable Features integration in Prismatic Machining and Advanced Machining products G Management of Recognized Prismatic Machinable Features in Manufacturing View (presentation, edition, highlight, and so on). Before Reading this Guide 2Page Prismatic Machining Preparation Assistant Version 5 Release 15 Before reading this guide, you should be familiar with basic Version 5 concepts such as document windows, standard and view toolbars.
