Final answer:
The advantage of a multi-wheel cutter is improved speed.
Step-by-step explanation:
The advantage of a multi-wheel cutter is improved speed. According to Figure 12.4, the three-blade design is the most efficient and has a lower tip speed compared to 2 or 1-blade designs.
This means that a multi-wheel cutter can cut materials at a faster rate. For example, if a single-blade design takes 10 seconds to cut through a material, a multi-wheel cutter might be able to do it in 5 seconds.
