Statistical Process and Quality Control (SPC/SQC)

For every product, the quality manager defines the quality and process control plan including the parameters to be monitored, the sampling strategy as well as the calculations to be used. A link with the PlantMaster scheduling software assures an automatic generation of inspection orders at the start of each production order. Production orders for which the quality checks are overdue are automatically highlighted by the system.

Process parameters are collected automatically using the Data Units at the machines (serial or Ethernet interface with the machine controller or analog inputs) while part related data is sampled directly from measurement devices such as scales and calipers or entered manually through an input program on a PC or a mobile device, such as a tablet or smartphone. BMSvision is reseller for IBR IMBus modular measuring bus equipment which are supported by the QMaster software. The IMBus technology features easy connection of multiple sensors, probes, scales etc to a computer, no matter which interface these devices have, for example Mitutoyo Digimatic, serial, analogue, Profibus.

The QMaster module offers an extensive set of reporting tools: control charts for variables and attributes, histograms and process capability calculations. For variables, the user can select from X-R, X-S and individual values charts. P, NP as well as pareto charts are available for attributes. The system automatically calculates alarm and warning limits.
