Project 01 Machine Vise DRAFT 124 Note: You may choose to draw a different assembly. Other possibilities include the assemblies shown of pages 459‐491 of your Technical Drawing, Giesecke, textbook. Process for completing Working Drawings Step 1 – Draw Parts (10 Parts and 2 Standard parts from the toolbox) Step 2 – Create Assembly Step 3 – Create Exploded View Step 4 – Create an Assembly Drawing including a Bill of Materials (BOM) Step 5 – Make detailed drawings of all the parts excluding the standard fasteners. Step 6 – Complete the tutorial for Photoworks and render the machine vise. Information contained in the drawing. Tolerances – Amount by which a dimension is allowed to vary. Upper and Lower limits given. Take average (nominal) value for drawing part in SolidWorks. Add the tolerances in the sketch or the drawing in the left hand control frame. Threads – Most commonly occur in fasteners such a screw, nuts and bolts. Figure 1 details how to read thread notes. Figure 1: Understanding thread notes Materials SAE #1020 – Standard naming convention for Carbon steel with alloys. SAE is Society of Automobile Engineers. Other naming standards for steels are AISI and ASTM. C1 – cast part. (manufactured using casting process). CRS – Cold Rolled Steel. Manufacturing processes Reaming – slightly enlarging a finished hole to give it greater accuracy. Tapping – cutting internal threads. Other acronyms CSK – Countersunk. FL HD MACH SCR – Flat Head Machine Screw. Drill sizes ‐ Drills are known by the standard numbering for different diameters. Refer Appendix table 18 page 831 of your textbook for various drill numbers. Submit B‐size assembly drawing, B‐Size rendered drawing and all the detailed part drawings. Please staple your sheets. Drop all part files, assembly file and assembly drawing file to the Instructor dropbox. Folder naming convention: LASTNAME_Last four digits of SID_PT01 For example my folder for Project #1 would be named: STUDENTNAME_1234_PT01
