List two reasons why machined parts often require a high degree of precision.
Gekata [30.6K]

Explanation:

Precision machining is a subtractive process used in cases where material needs to be removed from a raw product to create the finished product. Precision machining can be used to create a wide variety of products, items, and parts for any number of different objects and materials. These parts usually require tight tolerances variation from nominal dimensions and from part to part, which means that there is not much room for error in the production of the piece. Repeatability and well-controlled tolerances are hallmarks of precision machining. Components, parts and finished durable products that are designed to maintain extremely tight tolerance margins and a high degree of durability are essential and common drivers for utilization of precision machining. For example, parts that need to work together as part of a machine may need to always align within a certain margin of 0.01mm to 0.05mm. Precision engineering and machining help to ensure these parts can not only be made precisely but can be produced with this level of accuracy over and over again.

Use the image below to measure the blocks. Enter your measurement in centimeters accurate to the 0.1 cm.
SOVA2 [1]

Answer:

Pink block = 1.4 cm

Green block= 1.5 cm

Blue block= 1.7 cm

Explanation:

Hi, the ruler is in centimeters, from left to right each long line ( the ones with the number ) is a centimeter.

Since 10 millimeter equals 1 centimeter each short line is a millimeter (0.1 cm)

Knowing this, the measures of each block are.

Pink block = 1.4 cm

Green block= 1.5 cm

Blue block= 1.7 cm
