Abstract:
To research
cutting process in the non-eccentricity orthogonal turn-milling
machining, in allusion to the characteristic changed the cutting
thickness and deepness continually in the non-eccentricity orthogonal
turn-milling process, the cutting edge is divide into the circle edge
and the end edge, and the respective model calculating the instantaneous
cutting force is founded through researching the respective
instantaneous cutting area. And the process of the instantaneous cutting
force change is simulated through the mathematical model. It is shown
that the non-eccentricity orthogonal turn-milling is the process of
variable cutting force under multi-parameters, both the circle edge and
the end edge exert the important function on the cutting process, the
maximal value of the instantaneous cutting force is decided by the
cutting force on the circle edge and the end edge together, but the
cutting force on the circle edge is bigger than that on the end edge
obviously. The circle edge and the end edge almost cut in or cut out the
workpiece at the same time. The instantaneous cutting force on the
circle edge brings one break in one integrated cutting process, and no
break happen on the end edge.
Key words:
