Hole making is both a time- and tool-consuming process for many shops. Helical interpolation with indexable tooling is a great way to tackle this challenge quickly – and it's an especially advantageous approach when creating larger-diameter holes.
Although you can helix with a variety of tool types, high-feed takes its benefits to another level. Here, we'll machine a 4" diameter hole in 2.5" thick 4140 PH steel on a 40-taper machining center. Total cycle time? Just two and a half minutes, running somewhat conservatively.
Helical interpolation offers a crazy-fast way to machine holes, but there are benefits beyond your cycle times.
While high-feed tooling will generate a scalloped wall finish, it provides the shortest cycle times by far, and it works very well in more challenging long-reach scenarios.
