  "Specifications for metrology equipment are usually published in nice glossy brochures that have lots of great pictures highlighting all the features of the product. But specifications can be confusing and are often a hot topic of debate.  One of the good things about published specifications is in the fine print—the part that says the manufacturer has the right to change the specifications at any time. Why is it good that manufacturers can change their specs? Because, as we have discussed many times, there is an ever-increasing demand on machining to produce parts with tighter tolerances..."

But the importance of this concept—which results from the perpendicular intersection of lines or surfaces—applies to architecture, civil engineering, agriculture and manufacturing.  There are a number of different terms used to describe this relationship, including perpendicularity, 90 degrees, normalcy or squareness. In engineering products, which may not have perpendicular surfaces, the right angle is used in the dimensioning of rectangular coordinates. The implementation of perpendicularity in manufacturing and measuring is never perfect and is assessed as achieving a greater or lesser degree of perpendicularity..."

 "In some plants, metal parts are made accurate to 0.01 inch. In other plants, there are products that cannot tolerate size differences of even a few millionths of an inch. Making parts to either tolerance range is impossible without accurate gaging. However, accurate gaging is impossible if liberties are taken with the design, handling and maintenance of precision measuring instruments. Understanding the following nine major enemies of precision gaging will help defend your measurements against inaccuracy ..."
