Question

Load a tolerance table from a file from examples below. This will load a tolerance table and stimate gap sizes and tolerances.

The input to the program will be a text file containing the information for a tolerance table. An example follows using the values from the first lecture on tolerance analysis. These values will be stored in a text file. The data is comma delimited, which means that each data field is separated by a comma. If the first word is ‘PART’ the following values are the nominal size, +/- impact, tolerance, and fixed/variable. If the first word is ‘GAP’ the following values are the minimum and maximum sizes. (Note: assume all units are inches.)

PART,2.000,-1,0.050,V

PART,0.975,-1,0.025,V

PART,3.000,+1,0.010,F

GAP,0.000,0.080

These values will be processed using the method taught in class. A sample output for the first stage is given.

Actual Gap Mean: 0.025”

Actual Gap Tolerance: 0.085”

The Maximum Gap (0.110”) is (Greater) than specified (0.080”)

The Minimum Gap (-0.060”) is (Less) than the specified (0.000”)
