Machine changeover times can be really long depending on the complexity of the machine. In many cases, machine changeover times can be reduced by parallelizing the tasks at hand. A changeover process of several hours can therefor be shortend to less than one hour. This type of process requires a digital system since the coordination of many work items at once cannot be handled by a single person.
To reduce machine changeover times the process running times need to be shortened. If work steps are executed in a linear fashion, there is not enough optimization potential. Reducing a changeover process by a few seconds in each step only yields single digit improvements. A step change can not be achieved with making a barcode scan become 2 seconds faster.
Between a worker finishing a work procedure and a technician arriving to perform a machine changeover, there are usually several minutes of time being wasted. Maintenance technicians are not alerted ahead of time but only after a process has come to finish. In order to reduce wait times between processes, it is necessary to implement a system that can look ahead on upcoming tasks and schedules them accordingly.
Often paper documentation for changeover procedures is the norm on the shopfloor. Since a paper process is very static, technicians often are unable to avoid roundtrips to fetch spare parts or tools required for the job. A paperless maintenance procedure will adapt to the specifics of a changeover process and alert the technician ahead of time to fetch the correct tools and spare parts.
Implementing a digital machine changeover process is a standard feature of the WORKERBASE platform. The guideline for shortening machine changeover times is based on three fundamental steps:
A parallel execution of workflow steps can unlock enormous savings potential in a direct and indirect way. Quite often, the indirect savings offer the biggest potential.
