In generating grinding, part of the required modifications are applied to the wheel and another part to the grinding cycle. By interpolating several axes between the dressing tool and the grinding wheel during dual-flank dressing, the desired wheel profile is generated point by point, so that any type of profile desired can be created with no need for a dedicated roller.
The “disadvantage” to this type of cycle is that production setup times and dressing cycle are longer than in standard dressing.
The benefits become evident when comparing this type of machining with profile machining. While it requires longer dressing times, the process is faster than profile machining, and reduces both the risk of burns and production times.
