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.

The cutter has four teeth (cemented carbide inserts) and is 150 mm in diameter. The cutting speed = 2.8 m/s, and chipload = 0.27 mm/tooth. Assuming that the cutter enters the workpiece from its short side and follows a path that is centered over the workpiece, determine: i) the actual machining time to make the pass across the surface and, ii) the maximum metal removal rate during cutting.arrow_forwardWhat part of the vertical milling machine allows workpieces to be raised and lowered?arrow_forward
