Current Topic:
geometric tolerancing

One common area of confusion within GDT is between parallelism and flatness. With, parallelism, a reference is made to a datum plane, while flatness is independent of a datum. As specified, the opposite face of the block must lie within two planes which straddle a plane parallel to and a certain distance from the reference point in order to be calculated correctly.


My interest is on super duplex valves and other exotic alloy valves at The Alloy Valve Stockist, Barcelona, Spain.
