d) Datum

3. A large, flat plate with several holes to be punched by a CNC machine would be a good candidate for a style of dimensioning often called arrowless of _________ dimensioning.

a) Coordinate

b) Geometric

c) Tolerance

d) Dual

4. If a company manufactures a series of parts which have one dimension different, such as the length of the main body, one drawing can be used for the entire series by using _____________ dimensioning.

a) Size

b) Reference

c) Location

d) Tabular

Answer 1

1) option d - Broach is correct

All the other 3 have special symbol for local notes .

Symbol Counters in V Nepth ( deep) T Counter Bone

2) option b - chain is correct

chain dimensioning - In this each single dimension is placed directly adjacent to the next dimension without any gap between dimensions line.

Baseline dimensioning - In this features dimensioned from a common datum surface or feature.

Coordinarte or Datum dimensioning - these are useful on drawings needed to be machined by a CNC machine.

3) option a - coordinate is correct.

Coordinarte dimensioning is useful on drawings needed to be machined by a CNC machine.

Geometric dimensioning is done on the basis of Geometry or profile of the part

Tolerance dimensioning - It is based on the difference between the maximum and minimum limits.

Dual dimensioning - It is used on a drawing to show both inch and millimeter values for some or all of the dimensions

4) option b - Refernce is correct

In reference dimensioning , refernce is given to drawings to assist in knowing general distance information. marked by parentheses. should not be used for manufacturing or quality control
