3.2 Machining sequence planning
Properly determination of machining sequence is a key point in successful SPM
utilization. A poor machining sequence plan leads to lower quality of production and/or
increased machining times and consequently higher production costs. Often it is possible
to combine and perform a number of operations in a single setup lowering machining
times and costs while also improving production quality. Indeed machining sequence
planning determines the overall configuration of the machine and required machining
units and accessories.
