4. START-UP LOSS

Start-up losses are defined as time losses from
• start-up after periodic repair,
• start-up after suspension (long-time stoppage),
• start-up after holidays,
• Start-up after lunch breaks.
to the time when it is possible to produce excellent products of reliable quality, free from machine problems (minor stoppages, small problems, and blade breakdown) in a specified cycle time operation, as well as volume losses (defects/ rework) that arise during that period.

• Method of reducing start-up losses

– Time-series data at the time of start-up
– Examination of working oil/lubricating oil
– Examination of related equipment portions
– Adjustment of thermal displacement occurrence portions.
– Measurement of thermal displacement values
– Countermeasures
