Prototype Measurement

Measurement Aim. To assess if the production method proposed would produce flanges accurately enough to allow for the production of a 15 flange 1π ball arrangement. Single Flange Prototype made at Legnaro, and measured with a CMM at Daresbury. 3

Measurement Results

Measured deviation:

  • 0.004,+0.002,+0.007,+0.008,+0.013

670 θ

0.0214°error = 0.25mm 0.0128° error = 0.15mm 0.0086°error = 0.1mm 0.0043°error = 0.05mm

Ω

0.0521°error = 0.25mm 0.0313°error = 0.15mm 0.0209°error = 0.1mm 0.0104°error = 0.05mm Measured deviation:

  • 0.011,+0.0001,+0.0002,+0.0003,+0.0007

Conclusion. The prototype flange machined by LNL was well machined, Congratulations are deserved, care should be taken to maintain the accuracies achieved. 4
