The most impactful variables
Wire Diameter
Number of Bends
Angle
Impact of Wire Diameter
Increasing wire diameter leads to a proportional increase in the final length
Greater material deformation causes more significant changes in length
The stretch factor depends on specific wire dimensions and the chosen bending methods
Challenges Encountered
Precise measurement of final wire length
Using a thread is the most accessible option for precise measurement
Demands significant precision and accuracy but is susceptible to errors
Achieving Perfect Wire Bends
Achieving flawless wire/tube bends, especially at the exact position of the centerline radius, is inherently challenging.
