ADVANCED MATERIALS & PROCESSES | APRIL 2024 36 iTSSe TSS iTSSe TSS Workpiece identification utilizing QR codes permits the real time tracking of specific parts. The QR code can also assign a specific spray process and handling parameter recipes to be applied to permit coating of an assembly of dissimilar parts. The coating center has historical data from previous production steps to complement the coating process data to improve the process through expert systems and ultimately machine learning. Dedicated exits are used for quality control purposes or to extract parts that have been produced with process conditions that exceeded permissible process parameters. These smart automated torch and workpiece handling concepts permit optimal productivity. For example, brake disk friction ring surface coatings are produced with the spray torch operating in a fixed position and two robots equipped with grippers with integrated masks and drives controlling the disks’ rotation speed will alternately feed the rotating disks under the continuously operated spray jet, thereby, minimizing inactive time and overspray (Fig. 6). Spray feedstock can be delivered in containers with QR codes to permit integration of feedstock properties in the records of a quality management system (QMS). The collected quality data can be evaluated to finetune feedstock specifications and bound process limits, with the aim being to reduce reject rates, production time, and material costs. Utilizing expert systems, spray process parameters can be adapted to the actual properties of an individual powder batch. Also, further costs can be reduced by the finetuning of spare part replacement cycles. Finally, alignment of coating process with automation and expert systems along with the pre- and post-treatment processes permits optimization of the overall production process to meet final workpiece tolerances and specifications with variable inputs. ~iTSSe For more information: Alan Burgess, president and founder, Spraywerx Technologies Inc., 115-2433 Dollarton Hwy, North Vancouver, BC, Canada, V7H 0A1, 604.306.2061, aburgess@ spraywerx.com, spraywerx.com.
