kalenterointi

Kalenterointi (kalendarointi) is a Finnish term with several related meanings depending on context. The most common are scheduling/calendaring in planning and a technical process in materials processing.

In scheduling, kalenterointi denotes the act of planning activities and allocating them to specific dates and times on a calendar. It is a core activity in project management, event planning, and operations. Practically it involves prioritizing tasks, setting deadlines, and coordinating resources. Tools include physical calendars and digital applications such as calendar apps, project management software, and scheduling algorithms. Benefits include clearer timelines, reduced overlap, and improved efficiency; challenges include dealing with uncertainty and last-minute changes.

In manufacturing, kalenterointi (calendering) is a process in which a material, typically a polymer or rubber compound, is passed through a stack of rotating rollers to reduce thickness, improve surface finish, and impart uniform properties. The number of rollers, nip gap, temperatures, roll speeds, and the number of passes determine final thickness and sheet properties. Calendered sheets and films are used in packaging, coatings, laminates, and electrical insulation. The process requires careful control to minimize defects such as uneven thickness, orientation effects, roller marks, or strain hardening. Common variants include sheet calendering and film calendering; sometimes calender lines include chill or cooling rolls to set the material.
