Designing an Injection Mold from a Surface File Trong Chương 7, bạn nhập một mô hình vững chắc cho một khuôn tiêm hai mảnh. Sau đó bạn sửa đổi các mô hình để hoàn tất thiết kế. Trong chương này, bạn sẽ tạo ra một khuôn hai mảnh tiêm vững chắc từ một mô hình bề mặt nhập khẩu của một container. Bạn sẽ tổ chức công việc của bạn bằng cách sử dụng màu sắc và mức độ xây dựng. | Designing an Injection Mold from a Surface File 8 Designing an Injection Mold from a Surface File In Chapter 7 you imported a solid model for a two-piece injection mold. You then modified the model to complete the design. In this chapter you will create a two-piece solid injection mold from an imported surface model of a container. You will organize your work using construction colors and levels. You will build on skills that you learned in previous chapters and learn new skills such as Importing a surface model Solidifying a surface model Adding draft to solid faces Extracting surfaces from a solid Extracting edge curves from a surface Creating a ruled surface Trimming a surface to curves Creating a sheet solid by stitching surfaces Trimming a solid to a sheet solid Creating a solid drawing layout Mastercam Version 9 Solids Tutorial 201 Chapter 8 Exercise 1 - Importing a surface file In this exercise you will read an IGES file into Mastercam. The IGES file contains multiple surfaces that represent a container for which you will create a two-piece plastic injection mold. 1. Choose Main Menu File Converters IGES Read file. 2. Open from your working folder. The IGES Read parameters dialog box opens. 3. Check your settings against the following picture. Make any necessary adjustments. 4. Choose OK to convert the file.
