Abstract: A construction process management system includes storage units that store work information of work to be carried out during construction of a plant, and section information, period information, and system information associated with the work information. The section information indicates a section in which work is performed among plural sections in the plant. The period information indicates a period in which the work is performed. The system information indicates a system to which the work belongs among systems in the construction work. The construction process management system further includes a process chart generation unit that extracts work information for section information item and generates a section-based process chart showing a process of work for each section based on the period information, and a conversion unit that converts the section-based process chart into a system-based process chart showing the process of work for each system based on the system information.

Abstract: An indexable cutter insert for a rotary cutter includes a generally polygonal plate defined by a front face, a rear face and a plurality of side faces. The corner portions of the plate where adjacent side faces intersect one another are removed to provide respective corner faces. The plate has a plurality of main cutting edges each defined by the front face and a respective one of the side faces and a plurality of auxiliary cutting edges each defined by the front face and a respective one of the corner faces. Each side face serves as a relief surface of a respective one of the main cutting edges. A forward portion of each corner face remote from the rear face serves as a relief surface of a respective one of the auxiliary cutting edges. A rearward portion of each corner face remote from the front face is offset inwardly from the forward portion to provide a clearance surface. The clearance surface extends from the rear face to a plane generally centrally of the thickness of the plate.
