Execution quality control system

Execution quality control system for cylinders for brake-assist systems in commercial vehicles.

The IT system assists quality control workers in their measurements of the precision of production line machinery. The procedure involves checking the first and last manufactured component of a given batch and the generation of a report on their precise parameters.

The controller checks measures of the honing of components – their diameter, cylindricity, squareness, ovality and honing angle – and enters them into the system, to three decimal places. After completing all boxes regarding the first cylinder, the IT system allows the quality control worker to measure and enter values for the final batch component. After checking the preciseness of execution of batch components comes the process of printing 2D DataMatrix barcodes, which the controller affixes to the manufactured cylinders and the report sheet. Upon scanning the code, the computer system displays the appropriate report. In this way, missing DataMatrix code labels can be printed off and affixed to the appropriate component.

This computer-assisted execution quality control developed by HDF significantly sped up our client’s implementation of processes related to their quality standards. With the automation of the final production phase, workers handle their duties more effectively, avoiding errors resulting from simple mistakes.

Removing the human element increased manufacturing productivity and made workstations more user-friendly.

The use of automatic identification very clearly sped up the complaints procedure for supplied components. Production line errors are also more quickly rectified, thanks to the clear, precise reports provided by the system. They simplify the analysis of potential errors, and speed up the identification of causes and appropriate solutions.

The IT system was commissioned by a global supplier of safety and control system solutions for commercial vehicles. HDF’s custom solution for computer-assisted quality control is being used in a Polish factory in Wrocław.
