• The own moment of inertia calculation for hexahedron and cylinder The own moment of inertia of hexahedron and cylinder can be calculated by the next expression when the center of gravity is at the center. Refer the expression when the calculation of the moment of inertia at the center of gravity.

Moment of inertia at the center of gravity : The hexahedron of 0.500 x 0.400 x 1.000[m] which encloses the entire hand + workpiece is assumed. By the expression to calculate the own moment of inertia of hexahedron,

It is necessary to set the moment of inertia 

at the center of gravity when the entire size of the tool and workpiece is large enough compareing with the distance from the flange to the center of gravity position. Calculate the moment of inertia at the center of gravity roughly from the expression (Refer to the above-mentioned supplemen:"The own moment of inertia calculation for hexahedron and cylinder"), by approximating the entire tool in the shape of the hexahedron or the cylinder. If the weight of held workpiece is greatly different like in the handling usage etc, it is more effective to set tool load information on each workpiece and to switch the tool on each step according to the held workpiece. Set the tool load information in the state to hold the heaviest workpiece when the tool is not switched.

The center of gravity position

 the moment of inertia at the center of gravity of the entire tool can be calculated by the weight and the center of gravity position of each mass when the tool can be thought that the tool consists of two or more big mass like the twin gun system etc. 1. Divide the tool into some parts as the weight and the center of gravity position can be roughly presumed. It is not necessary to divide in detail. The tool is approximated in construction of rough parts. 2. Calculate the weight and the center of gravity position of the each parts on flange coordinates. It does not care by a rough value. Calculate the own moments of inertia of the big parts. (If parts are small, it is not necessary to calculate the own moments of inertia. Refer to above-mentioned supplement : "The own moment of inertia calculation for hexahedron and cylinder" for how to calculate the own moment of inertia.)
