Monitoring process inputs, analyzing data, and continuously improving manufacturing processes are keys to increasing productivity and accuracy. Renishaw’s Productive Process Pyramid approach to controlling CNC operations establishes checks and measurements before, during, and immediately after machining to control common-cause and special-cause variation. Simply measuring the output of a manufacturing process using tailgate inspection is typically not enough, and often too late to control all the variability.
The Productive Process Pyramid identifies opportunities to reduce operating and quality costs without investment in more machinery – allowing manufacturers to get the most out of machine tool investments.
To control process variability, precision engineering technol- ogy leader Renishaw offers its systems as a complement to high-productivity machining centers for improved manufacturing capability. A manufacturing cell machines an enclosure housing using measurement data and connectivity to enable highly automated, highly productive, accurate manufacturing. Cell data, measured by the QC20-W wireless ballbar, outlines the effects of machine tool performance on the quality of parts produced.
This technology allows rapid automated tool setting with the Renishaw NC4 and easy workpiece location using the SPRINT™ on-machine scanning system.
Renishaw’s Equator Gaging System uses robot handling and data connectivity to provide automatic tool offset control and point-of-manufacture quality assurance, keeping the machining process centered. When all machining and finishing processes are complete, Renishaw CMM inspection systems verify final part specifications. The machining cell lowers costs by around 64%, eliminating labor costs and increasing good part throughput.
