CAD/CAM

Overview:

CAD (Computer Aided Design): Software that allows you to draw a part in 3D space to better visualize features and geometry.

CAM (Computer Aided Manufacturing): Software that allows you to develop a toolpath to manufacture your part in a CNC machine.

Post Processor: A specialized file that converts the toolpath generated by the CAM software to code that a specific Make and Model of machine can understand.

BEFORE YOU BEGIN CREATING CAM OPERATIONS, YOU MUST CONSULT WITH A QUALIFIED BIDC TA OR STAFF MEMBER TO DETERMINE IF CAM IS NECESSARY AND WHAT CAM PROCESSES TO USE TO MANUFACTURE YOUR PART

Tool Library:

The BIDC has developed a custom tool library that contains all of the commonly used tools on the CNC machines. The library is divided into different sections based on the material to be machined.

  • Mild Steels (P)
  • Stainless Steels (M)
  • Cast Irons (K)
  • Nonferrous Metals (N)
  • Super Alloys (S)
  • Heat Treated Metals (H)
  • Plastics (Pl)
  • Woods (W)

The speeds and feeds for each tool are preset for you based on the material in the subsection and the characteristics of each tool. Do not adjust the speeds and feeds unless instructed to do so by a qualified BIDC TA or staff member.

Post Processor:

The BIDC has developed a set of custom post processors to work with our CNC machines. There are three separate post processors currently available

  • BIDC Haas Mill
  • BIDC Haas Gantry
  • BIDC Haas ST-20Y

The proper post processor must be selected when post processing code for use at the BIDC. The ST-20Y post is to be used for live tooling operations only. All standard lathe operations should still be created in IPS or VQC. The posted live tooling operations should then be copied and pasted into the main code using a text editor such as Notepad. Any standard lathe operations that cannot be completed using IPS or VQC should be directed to a qualified BIDC TA or staff member.
