2 Prepare a tolerance graph for the following part drawing O

2. Prepare a tolerance graph for the following part drawing. Only dimensions along the X coordinate are shown and considered in the problem. Is there any cycle or disconnect node? What are inferred distances between D-E, E-F, C-E? What are inferred tolerances between D-E, E-F, C-E? 0.01 140.01 3t0,01 0.01 840.01 B C

Solution

Given

A - C = 3

B - C = 1

C - D = 1

B - E = 4

A - F = 8

Solution

1. D - E = (B-E) - ((B-C)+(C-D))

                = 4-(1+1)

                = 4-2

         D-E= 2

Inferred tolerances between D-E = 0.01+0.01+0.01

                                       =±0.03

2. E - F = (A-F)-[(A-C)+(C-D)+(D-E)]

                =8-[3+1+2]

                = 8 - 6

                = 2

Inferred tolerances between E - F = 0.01+0.01+0.01+0.01

                                       =±0.04

3. C-E = (C-D) + (D-E)

                =1+2

                =3

Inferred tolerances between C - E = 0.01+0.01

                                       =±0.02
