milling motor 1) A vertical milling machine is visible on the figure located on the right. The machine has two axes. Motor 1 is rotating the piece while milling motor is moving in x direction to carve the metal piece to give form as a star. A 2cm diameter round piece is desired to be milled to create a star as depicted in the picture. a) Derive the cam profile between a (in degrees) and x (in cm), draw cam points. (Hint: use geometry properties of 6 corner star with triangles) b) What would be the suitable polynomial for this cam profile. Discuss. MOTOR 1 X Rotation -R 2.00 cm -R 1.15 cm
