Boring uses single point cutting tools which are straight vertical shaped.

Answer 2

Answer:

Parabolic curves is not used in Boring.

Step-by-step explanation: Parabolic curves are primarily utilised for converging or diverging light, as well as when radiation needs to be transferred from a single point into a broad parallel beam because radiation is frequently concentrated at one place (such as in radio telescopes, pay TV dishes, and solar radiation collectors) (e.g. headlight reflectors). In Boring, parabolic curves are not employed. Boring uses single-point, vertically oriented cutting instruments.

Hence, the correct answer is (c) Bornig.
