This document summarizes research into using high efficiency deep grinding (HEDG) for automotive crankshafts. Laboratory experiments examined material removal rates up to 2000 mm3/s on steel samples, measuring surface temperature and integrity. Production tests on steel and cast iron crankshafts achieved similar removal rates without thermal damage. Thermal modeling showed heat flux into the workpiece peaks then reduces with increasing removal rate. Microstructure analysis found no damage below 200mm3/s for steel or below 340 mm3/s for cast iron. HEDG can achieve high removal rates without thermal damage and improve component performance.

Understanding User Needs and Satisfying Them
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs
