128 Geometric Dimensioning and Tolerancing Print Reading Exercises Name _________________________________ The following print reading exercises use actual industry prints with related questions that require you to read specifi c dimensioning and geometric tolerancing representations. The answers should be based on previously learned content of this book. The prints used are based on ASME standards. However, company standards can differ slightly. When reading these prints, or any other industry prints, a degree of fl exibility is required to determine how individual applications correlate with the ASME standards. Refer to the print of the SLEEVE-DEWAR REIMAGING found on page 433. 1. Describe Datum A. ______________________________________________________ _______________________________________________________________________ 2. Describe Datum B. ______________________________________________________ _______________________________________________________________________ 3. Give the location dimension of the ∅.107±.001 hole from Datum A. ____________ Refer to the print of the BRACKET found on page 434. 4. Identify the datums that make up the primary datum reference frame. _________ _______________________________________________________________________ 5. Describe Datum D. ______________________________________________________ _______________________________________________________________________ 6. Identify the primary, secondary, and tertiary datum references associated with the positional geometric tolerance placed with the ∅.875±.005 dimension: Primary _______________________________________________________________ Secondary _____________________________________________________________ Tertiary ________________________________________________________________ 7. Give the location dimensions to the three ∅.437±.005 holes from Datum C. _______________________________________________________________________ 8. Give the location dimensions to the three ∅.437±.005 holes from Datum B. _______________________________________________________________________ 9. Give the location dimensions to the four ∅.187±.003 holes from Datum A. _______________________________________________________________________ 10. Give the location dimensions to the four ∅.187±.003 holes from Datum C. _______________________________________________________________________ 11. Are the location dimensions in question 7 placed using baseline or chain dimensioning? _______________________________________________________________________ 3
