What are Datum Feature Simulators? Datum Feature Simulators are "conceptually" perfectly perfect, or "physically" almost perfect, inverse Datum Features, which represent the mating Datum Features of a part or the staging surfaces of a manufacturing or a gaging fixture. Note: The Y14.5 2009 Standard does not define a Datum Target Simulator.
#DATUM REFERENCE FRAME SIMULATOR#
"Physical Datum Feature Simulator ( 1.3.17.2 p.3)": The physical boundary used to establish a simulated datum from a specified datum feature. Y14.5 2009 Definition: "Theoretical Datum Feature Simulator ( 1.3.17.1 p.3)": The theoretically perfect boundary used to establish a datum from a specified datum feature. DATUM FEATURE SIMULATORS & DATUM TARGET SIMULATORS In this column, we will address the remaining concepts, namely 4) Datum Feature and Datum Target Simulators, 5) Datums, 6) Datum Reference Frames, 7) Datum Reference Frame Components and Labels, and 8) Datum Reference Frame Mobility.Ĥ. In our last workshop we dealt with an initial set of the I concepts that impact the definition and establishment of Datum Reference Frames, namely 1) Datum Features, 2) Composite Datum Features and 3) Datum Targets.
