What is the overall width What is the overall height What is

What is the overall width? What is the overall height? What is the center-to-center distance of the 0.19 holes? Calculate the width of the casting before machining. At what angle to the vertical are the sides of the dovetail slot? How many different surfaces require finishing? Which type of lines in the top view represent the dovetail? What was the original size of the 1.50? How wide is the opening in the dovetail? How high is the dovetail? When was the 1.50 dimension altered? How many reference dimensions are shown? Calculate the distances A to S. What is the size and type of cap screw required to fasten the slide bracket to its mating part? How many not-to-scale dimensions are shown?

Solution

Assuming all dimesnsions are in inches

1. Overall width = 3.4\"

2. Overall height = Couldn\'t be evaluated from photograph

3. 0.19 in holes are not mentioned in drawing

4. Width of casting before machining = 3.4 inch

5. Angle at which vertical are to the sides of dovetail = 60 degrees

6. Sufaces requiring finish operation are 3 nos (Dovetail sliding surface - Shown with datum or inv delta finish)

7. Dashed/dotted lines show the dovetail in top view

8. Original size of 1.5 inch hole was 1 inch before. (Changed upon modification)

9. Width of dovetail = 1.4 inch (opening) and 1.79 inch (Sliding surface width)

10. Height of dovetail = 0.34 inch

11. Date of modification = Not mentioned in drawing. Could be taken that of the date of drawing.

12. No. of Reference dimensions = 2 nos. (horizontal and vertical near the circle)

13. A and S points not visible in drawing

14. A and B parts are not visible in drawing

15. Not to scale dimesions = Could be evalauted from photo
