QUESTION 11
Slitting is the operation of:
Removal of metal to the desired shape from the edge of a plate.
OCutting a sheet of metal through part of its length and then bending the cut portion.
Making incomplete cutting in a sheet of metal in a straight line.
Bending a sheet of metal along a curved axis.
Select all that is true about crosshatching, also known as hatching, hatch lines, and section lines:
Group of answer choices
Crosshatching is not used over cavities within the cut.
Hatch pattern standards exist for ANSI and ISO.
Hatch lines indicate cut material that came in contact with the cutting plane.
Different hatch patterns represent different materials.
Hatch patterns and directions should be identical in adjacent parts within sectioned assemblies.
Any hatch pattern can be used.
How many passes will it take to reduce the diameter from 5 % (five and one fourth) inches into 3 % (three and
three fourth) inch if the depth of cut is 1/16 inch.

Group of answer choices In orthogonal cutting, the cutting edge of the tool is perpendicular to the cutting direction. Continuous chips are typically formed at high cutting speeds and/or high rake angles. Continuous chips are always desirable because they produce good surface finish. In cutting, chip thickness is always greater than the depth of cut. PreviousNextarrow_forwardQuestion 9?arrow_forward
