homing procedure .......Answer.........1. Select home mode on MCU.
2. Select jog mode and use jog controls to move machine
components in the direction of the home position
3. Once the components are moving towards the home position,
most machines will complete the homing procedure automatically.
thermal expansion .......Answer.........increase in material's
dimensions when temperature rises.
work shift offsets .......Answer.........reposition the spindle in all
three axes. It applies to every tool loaded
,Page 2 of 16
tool length offsets .......Answer.........compensate for varying tool
lengths in the Z axis. Each tool has its own unique tool length
offset
cutter radius compensation (CRC) .......Answer.........adjusts for
varying tool diameters and affects a tool's position in the X and
Y axes only.
edge finder .......Answer.........used to determine work shift offset
for a part
touches off .......Answer.........Determine exact location of a tool tip
by touching it against an object with a known measurement.
G codes .......Answer.........allows operators to store multiple
workshift offsets in a MCU
how to measure tool length .......Answer.........measure from the
gage line to a tool's tip and then program this value into the
MCU.
, Page 3 of 16
With CRC... .......Answer.........CNC mill automatically adjusts for
the diameter of the tool along the X and Y axes before making
a cut. Since the diameter of the cutting tool is accounted for, the
finished workpiece will be within specifications.
without CRC... .......Answer.........CNC mill does not account for the
diameter of the tool before making a cut. The tool's diameter
may cause the cut to be outside specifications, resulting in an
unusable finished product.
A precise metal block with dimensions measuring 25.4 mm, 50.8
mm, and 76.2 mm long, respectively. A ___ ___ can be used to
touch off a tool during calculation of tool length offset.
.......Answer.........1-2-3 block
An imaginary line that passes through the center of an object.
___ are used to measure the distances of objects in the Cartesian
coordinate system. .......Answer.........axes
