The most important application of the cycloidal and involutecurves is in the cutting of all forms of gear teeth. It has been foundthat the teeth of gears when cut accurately to either of these curveswill mesh with the least friction and run with exceptional smooth-The development of these gears and of the machines for ness. cutting them has reached a high state of perfection. 120 MECHANICAL DRAWING 55 GEOMETRICAL PROBLEMS The problems given in Plates IV to VIII inclusive hav-e beenclioscn because of their particular bearing on the work of themechanical draftsman. They should be solved with great care, as theprinciples involved will be used in later work. PLATE IV Penciling.
