About this course The goal of this course is to teach you how to use SolidCAM’s Multiblade Machining to machine an impeller blade. This tutorial covers the basic concepts of Multiblade Machining. Once you have developed a good foundation in basic skills, you can refer to the online help for information on the less frequently used options. Prerequisites Students attending this course are expected to have basic knowledge of the SolidCAM software. Course design This course is designed around a task-based approach to training. The guided exercises will teach you the necessary commands and options to complete a machining task. The theoretical explanations are embedded into these exercises to give an overview of the Multiblade Machining capabilities. Using this book This tutorial is intended to be used in a classroom environment under the guidance of an experienced instructor. It is also intended to be a self-study tutorial.

1. Introduction
Multiblade Machining The Multiblade Machining operation easily handles impellers and bladed disks, with multiple strategies to efficiently rough and finish each part of these complex shapes. All the blade surfaces are machined in a single operation. Various cutting strategies are supplied for roughing and finishing of the impeller parts. Multi-bladed parts are used in many industries. This operation is specifically designed to generate the necessary tool paths for the different multiblade configurations. Some of the advantages of this powerful operation are: Powerful engine for machining impellers. Minimum inputs needed Automatic tool axis control Root fillets are handled with ease Different strategies for Roughing, Blade finishing, Fillet finishing, and Hub finishing
A Multiblade impeller has the following elements: 1. Hub surface 2. Main blade 3. Leading edge 4. Trailing edge 5. Fillet 6. Splitter 7. Shroud

CAM-Part Definition
2
The CAM-Part definition process for the impeller part consists of the following stages: CAM-Part creation
CNC-Machine definition
Coordinate System definition
• CAM-Part creation. At this stage, you have to define the CAM-Part name and location. SolidCAM defines the necessary system files and a folder to allocate the place to store SolidCAM data. • CNC-controller definition. It is necessary to choose the CNC-controller. The controller type influences the Coordinate System definition and the Geometry definition. • Coordinate System definition. You have to define the Coordinate System, which is the origin for all machining operations of the CAM-Part. You can create multiple CoordSys positions and in each machining step select which CoordSys you want to use for the operation. The following exercises describe the full process of the CAM-Part definition. It is recommended to go through the stages in order to understand how the CAM-Part features are built. For this purpose, you have to turn off the automatic CAM-Part definition. 1.
