We offer the following solutions leveraging the shipbuilding know-how that we have developed over many years.

•  Steel plate automatic nesting system (FINEST)
•  Steel plate bending work guidance system（IHI-α)
•  The Ajisai PC(IHI personal computer version Hull CAD/CAM system)

 

Steel plate automatic nesting system (FINEST)

Regarding the steel plates purchased, arrangement work of numerous free-form parts with good yield rate (nesting) has been mainly conducted manually in the past. This system realized the automation of this kind of manual work by the unique algorithm (FINEST) to accomplish the maximum yield rate, thereby, bringing significant benefits to reduce the man-hours and to boost yield. In addition, the function of material handling is incorporated in the system to determine the size of steel plate for purchasing.

 

 

The Ajisai PC (IHI personal computer version Hull CAD/CAM system)

This system outputs the information required for the bending work upon computer quantifying the heat positions or heat conditions by unique analysis methodology which were once the know-how of veteran workers. Main output information is as follows.

*Guidance information
(Plan of the fabrication method, Interim shape bending die information, Plate support height information)

*Management information
(Shape information, Working time information, Optimum plate splitting information, Shrinkage amount)
The validity of plan of the fabrication method was already verified by application to the parts of actual ship at IHI Kure Works.
