Following Brown & Sharpe's announcement of the close of the Standard Gage plant (Poughkeepsie, N.Y.), Dorsey Metrology International (also in Poughkeepsie) unveiled its intention to manufacture and support many of the Standard Gage products.
Dorsey acquired much of Standard Gage's specialized tooling and machinery at auction and subsequently hired several key former Standard Gage employees.
Because 10 identical patterns aren't typically available, the standard gage
R&R procedures must be modified for use in the pattern shop.
Standard gage elements comprise three main members, the leaf spring parallelogram, the air/spring actuated linear bearing slide and the X/Y coordinating table.
And if this is true, a family of standard gage bases can accommodate this range of parts.
"This premise is possible and standard gage bases have been designed to accommodate parts from the size of a dime up to the size of a two foot shaft that weighs 50 lb," says Mr Stout.
Note that both the standard Gage
R&R calculations and the proposed MSV are shown for comparison purposes, though the percent operator variation in the MSV calculation does not have the part correction that is shown for GR&R.
