Module 3 Unit 15 – Detail Drawings

Learning Objectives Explain terms and standards related to various types of drawings used in industry. Describe how detail drawings are defined and categorized in industry. Identify the unique characteristics of casting and forging drawings. Identify the unique characteristics of purchased part control drawings.

Learning Objectives Identify the unique characteristics of modifying drawings. Describe the unique characteristics of pattern development and welding drawings. List and describe other specialized types of drawings used in industry.

Two Types of Working Drawings Detail drawings contain complete information about producing a part Assembly drawings contain information about the assembly of two or more parts

Detail Drawings Includes: Name of the part Shape description Size description Notes Materials Special requirements

Detail Drawings Monodetail drawing: Contains complete information about producing one part Multidetail drawing: Contains information about producing two or more related parts; not very common, but allowable for situations such as specially matched parts

Casting Drawings Shows the dimensions necessary to create the mold of a cast part

Machining Drawings Shows the dimensions necessary to convert a casting into a finished part

Casting/Machining Drawings One detail drawing may show both the casting dimensions and the machining dimensions

Control Drawings Shows the specifications of a purchased part May serve as a bid document

Modifying Drawings Shows the specifications for making one part from another or for making changes to a part once delivered

Pattern-Development Drawings Shows the specifications for making the flat pattern of a folded part

Welding Drawings Shows the separate pieces that will be welded together Appears somewhat like an assembly drawing

Drawing Example

What are the two basic types of working drawings? Detail and assembly

What is the difference between a monodetail drawing and a multidetail drawing? A monodetail drawing contains only one part, while a multidetail drawing shows more than one multiview drawing on a single sheet.

List at least six types of detail drawings. Casting and forging, machining, purchase part control, altered-item, modification, pattern-development, welding, installation, selected-item, tube-bending, matched-set, and contour-definition drawings.

What is the difference between a casting drawing and a machining drawing? A casting drawing shows the dimensions necessary to create a mold of the part. A machining drawing shows the dimensions needed to convert a casting into a finished part.

What is the purpose of a purchased part control drawing? To document various engineering requirements to assure interchangeability of items each time they are purchased.

What does a modifying drawing describe? A part that is manufactured not from raw materials, but by altering another part.

Why would a pictorial view be shown on a pattern-development drawing? To show the part in its folded (finished) state

What does a contour-definition drawing show? The data needed to define or build a contoured or sculpted surface
