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. Make this machine, and display;
please give a solution with given condition.
