SPC

Goal driven inspection. Employees no longer have to work from individual documents as inspection characteristics, inspection notes, work instructions and drawings can be displayed side by side on screen.

Less is more

iqs Statistical Process Control (SPC) provides a basis for production accompanying inspection, process regulation and control as well as intermediate testing. The inspection can be triggered by both current manufacturing process and the inspection order. The optional feedback into the FMEA program optimizes continual inspection. All results obtained can be used not only to assess the current quality situation but additionally they further the knowledge pool of your business. Both the Inspection Plan and Control Plan modules support the control over how your processes are handled.

Recording test data

Graphic references (photos, drawings, videos, PDF documents etc.) support the entry of measured values for characteristics to be inspected and are displayed by the iqs drawing integration. Via electronic measuring equipment the measured values can be recorded automatically. Depending on the responsibilities of the inspector, he/she can independently develop inspection plans and react accordingly to deviations. The measured data is immediately available for all sorts of analyses.

Control center

The control center offers an efficient way of monitoring all production accompanying inspections. As well as planning inspection orders, the control center also evaluates random sample inspections thereby informing the person responsible about the quality of production. Through the comparison of different SPC and attribute charts, production parameters can be optimized and the best machines for a particular tool be chosen. The control center displays the manufacturing structure including the production area, machines as well as tools and assigns the components to corresponding inspection plans. From the inspection plans created by iqs PP/CP, the desired SPC charts are automatically generated and versioned. The necessary employees can be automatically informed via email about events such as control limits being exceeded.
