TECH 104 – Technical Graphics Communication Week 11: Isometric Sketching
TECH 104 – Technical Graphics Communication First, Here’s what we talked about last time…Working Drawings
TECH 104 – Technical Graphics Communication Generally, a complete set of Working Drawings for an assembly includes: 1. ) Detail Drawings of each non-standard part. 2. ) An Assembly or Subassembly drawing showing all the standard parts in a single drawing. 3. ) A Bill of Materials (BOM). 4. A Title Block.
Assembly Drawing of a Piston & Rod containing 8 parts. An assembly drawing normally consists of the following: 1. All parts drawn in their operating position 2. A parts list or Bill of Materials (BOM) 3. Leader lines with balloons indicating all parts. 4. Machining and assembly instructions Also, Part Numbers (of individual parts) It’s own Drawing Number
Detail Drawing of the retainer ring used to fasten the rod to the piston.
TECH 104 – Technical Graphics Communication A Closer Look at Title Blocks They Contain: A. B. C. D. E. F. G. H. I. J. K. L. M. N. O. Name & Address of Company Title of the Drawing Number Names and dates of drafters, checker, issue date , contract number, etc. E. Design Approval F. Additional Approval Block G. Drawing Scale H. Federal Supply Code for Manufacturers J. Drawing Sheet Size K. Actual or estimated weight L. Sheet Number
TECH 104 – Technical Graphics Communication And Attached to Title Blocks…Parts Lists The information normally included in a parts list is as follows: 1. Name of the part. 2. A detail number for the part in the assembly. 3. The part material, such as cast iron or bronze. 4. The number of times that part is used in the assembly. 5. The company assigned part number. 6. Other information, such as weight, stock size, etc.
