Abstract: In order to improve the crankshaft machining efficiency, avoiding
the accumulated error caused by multiple clamping, this article mainly deals
with the solution of machining the outer circumference of the eccentric
crankshaft connecting rod neck and the crankshaft connecting rod neck opening
surface, and further studied and explained the macro programming method
suitable for the turning and milling compound center. Along with the continuous
application of turning and milling compound center, the idea of single clamping
and complete processing is especially suitable for crankshaft manufacturing, it
can improves the overall quality of the crankshaft.
Keywords: macro program; five-axis turning and milling compound center;
tangential feed point calculation; connecting rod outer circumference; open
surface; machine coordinate
