When stylus A is moved along curve y=f(x) in, slider 1 moves along sliding link 2 which travels with translational motion parallel to axis x-x. At this, pin a of slider 1 turns slotted link 3 about axis B. If the profile of the slot of link 3 is expressed by the equation y=r= r₀(sin(β))^(1/3) then the angle of rotation φ, of measuring wheel 4 is proportional to the quantity (1/r₀)^(n)∮(y^(n))dx.
