چکیده
|
This paper deals with hole-enlarging multi- flute drilling process. in this respect, the analysis of existing structures, their advantages and disadvantages is carried out and investigated. cutting conditions during hole-enlarging multi- ute drilling process are shown. herein, a new design of a hole-enlarging multi- ute drilling, as a holeenlarging multi-fl ute drill-broaching tool from broaching-speed steel with carbide plates, and a new way of handling new tools are presented. hole-enlarging multi-flute drillbroaching combines the features of hole-enlarging multi ute drill (in cross-section) and those of broaching tool (in longitudinal section). in so doing, it is possible to increase the quality of hole-making (size variance, surface roughness) to facilitate cutting conditions and increase durability. the results of prototypes testing are presented in the end.
