Head operation

To change the orientation of the probe

• Unlock the head by turning the lock lever to the fully anti-clockwise position
• Grip the body of the probe (avoid touching the stylus) and rotate the B-axis until the desired angle indication on the scale (in increments of 15°) is adjacent to the B-axis reference mark
• Rotate the A-axis until the desired angle indication on the scale (in increments of 15°) is at the A-axis reference position
• Lock the head by turning the lock lever to the fully clockwise position
• Qualify the stylus tip(s) according to the CMM supplier's instructions
• Change the orientation of the probe to the next desired position and qualify the stylus tip(s)
• Repeat the qualification process for all desired orientations and stylus tips
• Commence gauging, ensuring that the correct qualification data is recalled for each head position

Periodic requalification should be performed according to the following considerations:

• CMM supplier's recommendations, particularly in respect of temperature changes
• At the start of the working day or shift
• After an accidental collision
• After changing any measuring system component (except a prequalified TP20 module)
• If the initial state is unknown or uncertain
