Introduction Woven bags are widely used for the packaging products such as rice, flour, cement, fertilizer, chemical materials, metal products and so on.
The production of these materials is very great.
There are some advantages by using robot load-unload materials, such as gripping reliably, moving flexibly, placing neatly and so on.

Introduction Materials with high hardness and high toughness are ideal for cutting tools.
Three kinds of milling insert of different materials are chosen in the stainless steel cutting force experiments.
The ultrafine-grain waved-edge insert is very suitable to cut difficult-to-machine materials.

Fig. 1 Representative volume element for granular material Microstructure Characterization of Granular Materials The microstructure of granular materials is generally characterized by coordination number, contact normal, contact force and contact displacement, as shown in Fig. 1.
Deformation of granular materials is accompanied by significant changes in the magnitudes of contact forces.
Various interpretations of strain tensor for granular materials have been proposed based on different assumptions.
Fabric tensor in granular materials [C].

Organic materials (cable particularly) aging has an adverse effect on the safety of production situations, and it is unscientific to replace organic materials blindly.
A live evaluation system of organic materials aging was developed in present paper.
Another method is based on physical detection, ssuch as elongation at break (EAB) and compressive modulus of cable materials [4].
Compressive modulus of organic materials is the ratio of force to distance.
(5) It can evaluate not only cable but also other organic materials
