Learning what the most common errors are in creating or reading engineering drawings-and then learning how to avoid them altogether-has untold benefits for all engineers, technicians and draftsmen, be they mechanical engineers, product designers, manufacturing engineers, structural engineers, machinists, or others involved the technical graphic information for component, machines and systems. Based on a reference worked developed for engineers and technicians at Lockheed Martin, readers will find invaluable tips on: — How to understand the data on a drawing — How to avoid dimension and tolerance errors — How to select the proper drawing type for a given engineering objective.
All engineering drawings contain some errors. But the job of any engineer or enginnering technician is to try to make as few such errors as possible. This new book by the seasoned engineer Ronald Hanifan, shares insights in to what the most common types of errors are and and what steps to take to help ensure that they don’t happen in the first place. Readers will find
- A quick overview of common types of drawings- from Assembly Drawings to Detail Drawings to Vendor Item Drawings to Procurement Control Drawings.
- Understanding the most common errors in drawings- particularly Dimensioning and Tolerance errors.
- Checklists to review for common types of errors introduced at different stages in a drawing’s life.
Knowing how to follow simple but stringent quality control steps when creating and review-ing engineering drawings can save time and avoid often very closely mistakes.
