……………………………………………………………………………………………………… 265 Creo Parametric Basic Turning 5/265 CREO PARAMETRIC INTERFACE 1.1 This book This book is a follow-up to the books Creo Parametric Modeling and Creo Parametric Basic Milling 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 process It is also important to understand the elements that make up completed manufacturing models Download site: http://www.gold-cam.fi/en/download Or inquire: gold-cam@dlc.fi www.EngineeringEBooksPdf.com Creo Parametric Basic Turning 256/265 Click FINISH_OPER_2 Click File Select the MCD File check box, and click Done Click OK to create a CL data file named finish_oper_2.ncl Click Done Click UNCL01.P15 to select the post-processor Click Close in the information window Click Done Output View the contents of the browser This completes the procedure Task 5.2.2 is ready www.EngineeringEBooksPdf.com www.EngineeringEBooksPdf.com Creo Parametric Basic Turning 257/265 5.3 Post Processor Testing As mentioned, post-processing is the final stage in the manufacturing process and most important also The final NC Code is combination of the NC Sequence parameters and Postprocessor functions For example thread turning If you are using type AI MACRO, you will get 698 lines of NC Code using UNCL01.P15 lathe postprocessor If you select ISO output, you will get 21 lines of NC Code In addition, there is significant difference in the postprocessor definition You can open the NC Post Processor from the Applications tab when the manufacturing session is open Open the MORI SEKI SL 1 Option File: www.EngineeringEBooksPdf.com Creo Parametric Basic Turning 258/265 Select Machine Codes drop down menu and Thread Formats: Check the Output G76 threading cycle check box Save the Option File Now the thread NC Sequence is generated with the Mazak Quick Turn post processor (not in the default list) The code is not ready, but there are only a few lines of code The customizing of the post process is a big project and it needs own book later This completes the procedure www.EngineeringEBooksPdf.com Creo
