mg F F Gripping force at least 10 to 20 times the work piece weight The "10 to 20 times or more of the work piece weight" recommended by SMC is calculated with the safety margin of a = 4, which allows for impacts that occur during normal transportation, etc. 2F mg Number of fingers and therefore, mg F 2 x With "a" as the safety margin, F is determined as follows: mg F = x a 2 x When
Calculation example Calculation for allowable external force (with moment load) When static load f = 10 N, which produces pitch moment to the point L = 30 mm from MRHQ16D guide, is applied. Operable condition requires that F be bigger than f.
