Abstract: Steel grating is widely used in construction, chemical industry, water conservancy
and other fields. There are many problems in its design and manufacturing process that restrict the
production efficiency. The system integrates the functions of automatic SG-Layout, automatic
workload calculation, optimization for cutting and so on to optimize the whole process of design
and manufacturing of steel Grating. This greatly improves the efficiency of production. A project
example is given to prove the practicability and reliability of the system.

Key words: steel grating, CAD/CAM, automatic steel grating layout, optimization for
cutting
