DML Test 2 Advanced Lathe Operations | 60 Questions with 100% Correct Answers | Updated & Verified

you have a rectangular workpiece that needs a facing operation plus center drilling, and a universal chuck is mounted on the lathe spindle. What is your procedure to prepare for machining? - a lathe board is placed on the ways under the chuck, and the chuck removed, because it is the wrong chuck to hold rectangular work. The mating parts of an independent chuck and the lathe spindle are cleaned and the chuck is mounted. The part is rouchly centered in the jaws and adjusted to center by using the back of a tool holder or a dial indicator Should the point of the tool be set above, below, or at the center of the spindle axis when taking a facing cut? - center If you set the quick-change gearbox to .012 in, is that considered a roughing feed for facing? - no, the resultant facing feed would be approximately .003 to .005 in which would be a finishing feed An alignment step must be machined on a cover plate .125 in, +- .003 in, in depth. What procedure should be taken to face to this depth? how can you check your final finish cut? - the compound must be swung to either 30 or 90 degrees so that the tool can be fed into the face of the work by a measured amount. A depth micrometer or a micrometer caliper can be used to check the trial finish cut
