Calculations for Amplitude Adjustment

Calculations needed for using an Amplitude Adjuster are based on the data in the table below.

Input fields are  colored .

Fixed Values These are based on your machine
Headstock Lever Arm Length "

mm Distance from the headstock's pivot point to the center of the spindle
Amplitude Adjuster Lever Arm Length "

mm Distance from the amplitude adjuster's pivot point to the center of the spindle
Amplitude Adjustment
Amplitude Adjustment % At the given diameter, the resulting amplitude of cuts will be this percentage of the rosette's actual amplitude.
Estimated Rubber Distance Down

"

mm The distance the rubber is adjusted down from the center of the spindle. (This is the red rubber in the picture below.)

If the rubber is raised above the spindle, then this a negative number.

The AA Rubber (the blue one in the picture to the left) is aligned with the spindle axis.

The Rubber (the red one in the picture to the left) is moved up or down to adjust the amplitude.

The amount that this rubber is set below the spindle axis is the measurement used above in the field, Rubber Distance Down.

The measurement for Headstock Lever Arm Length and Amplitude Adjuster Lever Arm Length remains fixed for the machine you are using.

The measurement for Amplitude Adjuster Lever Arm Length remains fixed for the amplitude adjuster you are using. (If you have multiple AAs, use the measurements for the one you are using.)
