Mastercam Version 9 SolidsTutorial - Part 9

Designing an Electrode Trong chương này, bạn sẽ tạo ra một điện cực với hình dạng của các bế tắc từ lõi mốc mà bạn đã tạo ở chương trước. Điện cực sẽ được sử dụng trong một sụt giảm, hoặc chết chìm, EDM (Điện Discharge Machining) ứng dụng để tạo thành một khoang trong phôi. Lưu ý: Một tập tin sao lưu có chứa cốt lõi khuôn mẫu đã được cung cấp với các phần hướng dẫn khác trong trường hợp bạn đã không hoàn thành Chương 8. . | Designing an Electrode 9 Designing an Electrode In this chapter you will create an electrode with the shape of the standoff from the mold core that you created in the previous chapter. The electrode will be used in a plunge or die sinking EDM Electrical Discharge Machining application to form a cavity in a workpiece. Note A backup file containing the mold core was provided with the other tutorial parts in case you did not complete Chapter 8. You will build on skills that you learned in previous chapters and learn new skills such as Creating a sheet solid by removing a solid face Using a solid face to define a construction view Thickening a sheet solid Creating non-associative disjoint bodies Exercise 1 - Creating a sheet solid from the mold core In Exercise 4 of Chapter 8 you created a sheet solid by stitching together surfaces whose edge gaps were too large to form a closed solid body. In this exercise you will create a sheet solid by removing a face from a closed solid the mold core . Mastercam Version 9 Solids Tutorial 251 Chapter 9 Preparing the part You will hide all geometry except for the mold core and define a level on which to create the electrode. 1. Choose Main Menu File Get. 2. Select container-mm.mc9 from your working folder and choose Open. Note If you did not complete Chapter 8 open container-backup-mm.mc9. 3. Press Alt S to turn on shading. 4. Press Alt E to access the Hide function. 5. Select the light blue solid mold core and choose Done. Only the mold core remains in the graphics window. 6. Press Alt 2 to open the Level Manager. 7. In the Main Level section of the dialog box enter 6 for Number and Electrode for Name. 8. Make level 4 visible and levels 1 2 3 and 5 invisible. 9. Choose OK to close the dialog box. 252 Mastercam Version 9 Solids Tutorial Designing an Electrode Exercise 2 - Reducing the size of the Y-shaped cavity In this exercise you will reduce the size of the Y-shaped cavity. Doing so makes the electrode smaller which compensates .
