5-axis control machining can create workpieces with complicated shape
difficult to machine by 3-axis control. Moreover, 6-axis control machining
can cope with workpieces impossible to machine by rotational tools
since it can control the direction of non-rotational tool.
Though 5-axis control machining which uses rotational tools is advantageous
in terms of the machining efficiency, the cutting remainings peculiar
to the rotational tool take place at the corner part of workpiece shape.
On the other hand, 6-axis control machining can machine the corner part,
which cannot be removed with the rotational tool,
though it has the low machining efficiency. The use of two machining methods
together seems to be very effective to improve the machining efficiency.
This research investigates the highly efficient and accurate machining
method using 6-axis control machining together with 5-axis control one.
The algorithm to generate the cutter location data is developed
in consideration of the use of 5-axis and 6-axis control machining,
and it is implemented to the integrated CAM software for 5-axis and 6-axis
control machining. As a result, it is experimentally found that
the system enables the effective and accurate machining.
