1 Improving Spindle Up-time with the Right Workholding Michael Gaunce Group Manager, Stationary Workholding

2 Agenda Importance of Workholding & What IS Workholding Scope & Definitions Part Clamping Part Density Change-Over 2 IMTS 2018 Improving Spindle Up-Time with the right Workholding

3 Importance of Workholding Serve your customer better Better lead times (better efficiency overall, more flexibility across machines) More flexibility (easier reaction to emergencies, etc..) Competitive pricing (lower part run-time, lower burden-rate) Improve profitability Increased through-put (faster part processing, higher spindle efficiency) Higher spindle efficiency (longer run times between doors open & faster change-over) Better human resource efficiency (one operator running multiple machines) Improved ergonomics & ease of use Less part-handling (less operations) Improved safety (safety enhancements / part presence monitoring, etc..) Improved reliability / repeatability (rely on offsets, rely that the part is where you said it was 5 part-runs ago) 3

4 Aspects of Workholding How the part is clamped Affects number of operations required Affects quality / accuracy of final product How many parts are clamped Decrease the door open time Operators manning multiple machines How fast is the change-over Time for part-clamping / loading Time for complete change-overs 4

5 Scope & Definitions Workholding Stationary Workholding Mills Rotational Workholding Lathes 5

7 Clamping the Workpiece 7

8 Direct workpiece clamping 8

9 Goals when Clamping the Workpiece Maximize Accessibility Clamp Securely Trends in Mechanical Clamping: 1. High-grip, serrated jaw clamping 2. Dove-tail clamping 3. Direct work-piece clamping (modular workholding) 9

10 High-grip serrations 10

11 High-grip serrations 11

12 Dovetail Workholding Offers similar advantages to the high-grip serrations, but also gains the mechanical advantage of the dovetail shape Ideal against high pull-out forces, especially in Titanium Requires additional prep operation 12

13 Direct Workpiece Clamping (Modular Workholding) Similar idea to dovetail (actually preparing the workpiece for workholding) Ideal for larger parts Highly utilized in aerospace & tool/die Also popular for engine blocks in transfer lines 13
