| When castings with surface scale are being turned in an engine lathe, how is the first roughing cut taken in terms of depth of cut and feed? |
| A) a relatively light depth of cut only deep enough to incrementally remove the scale in several passes along with a relatively fine feed |
| B) a relatively heavy depth of cut deep enough to get under the scale should be used along with a relatively fine feed |
| C) a relatively light depth of cut only deep enough to incrementally remove the scale in several passes along with a relatively coarse feed |
| D) a relatively heavy depth of cut deep enough to get under the scale should be used along with a relatively coarse feed |
