Advanced Probe Designs

Question 1

What’s the difference between scanning probes and point-to-point probes?

Answer 1

Scanning probes brush against the surface rather than touch and beep every time it touches

Question 2

What’s the difference between 3 axis and 5 axis probes?

Answer 2

1) 5 axis uses a motorised probe holder rather than standard one
2) 3 axis probe can be tilted but remains fixed during scanning but the 5 axis can operate in all 2 axes during scanning

Question 3

Whats the difference between conventional touch probes and scanning probes

Answer 3

Conventional tour probes record the increase in resistance due to contact between stylus and part which causes deflection of stylus seat, the amount of tilt and direction of tilt is not determined
Scanning probes determine the amount and direction of tilt caused by this contact.
