Haas Discusses Directional Hole Tapping
Haas Automation explains how users should carry out directional hole tapping. A user may often need to complete an extra setup for that one hole at an angle to the surface machined or perhaps a radial hole on a circular component that requires drilling and tapping. One way to overcome extra setups is to use a fixed-angle tool or an adjustable tool for the most flexibility. While these tools are readily available from most tooling suppliers, the difficulty can be with the canned cycles in the machine. These drilling and tapping cycles make the assumption that the drilling or tapping action is going to be performed in the Z-axis direction, which is fine for the majority of cases but is unlikely to be the case. The programmer could write specific sub-programs and use a floating tap holder to allow for the change in spindle speeds through the tapping cycle. However, if using a Haas machine, he or she has the general-purpose tapping cycle, G184 for CW tapping, designed by Haas's contro...
