Precitech introduces PEPS II-VX, a digital non-contacting, height control and active vibration cancellation system jointly developed by Precitech and the vibration experts at TMC.

Thursday, February 11, 2016

Goal:
Demonstrate part cutting time, surface finish, and form accuracy achievable by 3 axis ruling on a Freeform® L equipped with PEPS II-VX, an active on machine vibration cancellation and precision leveling system.

Process:
XYZ ruling on a Freeform® L. The part was fixtured on a 45° slope between X and Z and 45° from horizontal, requiring the ruling process to utilize 3 linear axes simultaneously

Part Details:
• Material: Nickel phosphorus plated steel
• Part dimensions: 50 mm x 50 mm
• Machined area: 10 mm x 50 mm

Process Details:
• Tool: 1.5 mm radius
• Feed rate: 500 mm/min
• Finish pass depth of cut: 5 µm
• Step over: 5 µm
• Coolant: Odorless mineral spirits (OMS)

Results:
• Cutting time with PEPS II-VX: 8 hours*
• Cutting time to achieve similar surface finish results without PEPS II-VX: 16 hours
• Surface finish: 2.64 nm Sa
• Form accuracy: 0.113 µm PV** 0.024 µm rms
