Small and single batch production, particularly for large (some cubic metres), heavy (several tons), and complex workpieces, is still a challenge for machine tools users.
To achieve high product quality, timely QC (Quality Control)-production loops are required, which are inefficient and expensive.
The organisation and sequencing is also difficult because the process performance practical knowledge is almost unavailable.
As a consequence, this type of production is still affected by inefficiencies and waste (energy, raw material and time).
SOMMACT approaches these issues by the detection (in-process embedded traceable measurements) and compensation (adaptive control and self-learning) of geometrical effects of varying external and internal quantities, such as temperature gradients and workpiece mass.
