|In mechanics, the moment of inertia, or mass moment of inertia, expresses the difficulty in changing the motion state of a rotating body. The unit is typically Kg.m2 (kilogram times square meter). The further the mass is from the center of rotation, the greater the moment of inertia.
Calculating the moment of inertia for your assembly is crucial for determining the best indexing table for your needs, without risking oversizing and incurring excessive costs, or undersizing and not meeting the required resistance. There are several ways to determine the moment of inertia:
a) manually, using mathematical calculations
b) using our website (menu quote)
c) with CAD software (Solidworks, Inventor, Catia, NX, etc…)
We’ve created the step-by-step guide below to help identify the moment of inertia of your assembly that will be moved by the indexing table, using the CAD tools Solidworks and Inventor. Other CADs have similar methods for this calculation. Please consult your CAD manufacturer for the exact procedure.
