Planning generates a production order based on customer needs.
Setup start and Approval request
The toolmakers in the production department use a palmtop to notify the setup start stages, during this stage, moulds and all auxiliary equipment are fitted to the machine and it is possible, using a palmtop to causalise all downtime that was unforeseen during the setup.
Once the assembly stages have been terminated, the fitter (also via palmtop) will request approval to commence BAP production.
The computer system will generate an alert for the quality departments and the process control team commences the conformity procedures based on envisaged specifications.
Once complete, the BAP activity is recorded on the computer system and only after this, mass is production authorised.
Production commences and from this point the OEE is monitored, along with availability, productivity, and quality.
During production the parameters affecting OEE are identified and therefore:
Availability: % index measuring losses caused by significant machine downtimes, also known as justified stoppages. A low % value means that there have been high levels of machine down times
97% - Average availability
Productivity: the index measuring losses caused by the real operating speed as against the theoretical one. This also considers brief stoppages, known as unjustified micro stoppages. A low % means that actual operating speeds (machine cycles) are higher than in theory.
95% - Average productivity
Quality: this is an index measuring losses caused by production waste. It compares waste parts with the total number of parts made. A low % value means that the production waste levels are too high.
