PROBLEM 12.48 Advanced half and full sections

from actual industry drawing (in.)

Part Name: Diffuser Casting

Material: Titanium

SPECIFIC INSTRUCTIONS:

Convert all dimensions to ASME Y14.5-2009 standards as

shown and discussed in this text. Display the casting

material using phantom lines as shown in the engineer’s

layout. Use ANSI standard cutting-plane line.

ALTERNATE INSTRUCTIONS:

Omit phantom line technique for showing casting and

make two drawings: one a casting drawing with only

casting information, and the other a machining drawing

with only machining dimensions and information. Refer

to Chapter 4 for a review of this practice.

NOTE: Use dimensioning symbols based on the ASME

Y14.5-2009 standards described in Chapter 10 Dimen-

sioning and Tolerancing. This problem drawing is

based on an outdated standard using abbrevia-

tions and words that should be converted to

symbols as shown in Chapter 10.

Part 8: Problems 12.52 and12.53

PROBLEM 12.52 Removed sections (in.)

Part Name: Extension Bar

Material: SAE 4320

SPECIFIC INSTRUCTIONS: This part requires at least three re-

moved sections. A front and top view is recommended, and the

recommended section locations are identified. Use conventional

removed section cutting planes and place the removed sections

in alphabetical order from left to right.

PROBLEM 12.53 Removed sections arrow method (in.)

Part Name: Extension Bar

Material: SAE 4320

SPECIFIC INSTRUCTIONS: Use the same drawing found in Prob-

lem 12.52. Use the removed section arrow method for solving this

problem.
