Programming of CNC Machines, Third Edition

Part 6: Computer Aided Manufacturing from Solid Models

OBJECTIVES

  1. Become familiar with EdgeCAM CAD/CAM capabilities.

  2. Become familiar with the EdgeCAM User Interface.

  3. Learn terminology specific to Solid Modeling for CAD/CAM.

  4. Learn how to use Solid Model files to create tool path and CNC program code.

  5. Create CNC Machine Setup instructions from a CAD/CAM program.

SOLID MODELING BASICS

Solid Modeling of machined parts is becoming the method of choice for design to manufacture. It has great power and flexibility to aid the implementation of the model to metal concept. The designer has freedom to modify designs with ease and all related dimensional characteristics will automatically be updated to include the changes. This carries over to the CAM program as well. Once the adjusted file is opened again, after any changes, the program recognizes that changes have been made to the original and asks the user if the existing file should be updated to reflect these changes. This speeds the process when changes are necessary and that is nearly always. The software for Solid Modeling is very user friendly and machinists, programmers and design engineers learn to use its power fairly quickly.

In this section, we will examine a popular CAM program. With EdgeCAM Solid Machinist users can insert, open or drag-and-drop native files from other Solid Modeling software such as: Solid Works, Autodesk Inventor, etc. without the need for translators. Seamless and reliable integration means less chance for errors, making it an excellent choice for yielding quick productivity gains.

Solid Models are Feature Based Parametric designs. A feature is...
