- E Expert Q&A 1. Shaper (#X) Machine function and design requirements: The main function of this machine is to make surface more smooth; The required movements are: Reciprocating movement of planer knife and feed movement of the bow. It is required that the cutting speed is uniform, while the quirkily return is included. The basic data is: principal axis rotation speed is 60 r/min, the max length is less than 450 mm, the distance between working surface and the floor is 800 mm. Travel speed ratio co-efficient is 1.5, allowable pressure angle 15°, cutting quantity is 0.1~0.5 mm. Requirements: 1. Freedom calculations; 2. Force analysis; 3.
