NIMS CNC Operator Test Study Guide
+10 FEEDRATE - ANS-An override key on the Haas control that increases the current
feed rate in 10% increments.
+10 SPINDLE - ANS-An override key on the Haas control that increases the current
spindle speed in 10% increments.
100% FEEDRATE - ANS-An override key on the Haas control that sets the feed rate
back to 100% of the programmed value.
100% RAPID - ANS-An override key on the Haas control that allows the machine
spindle to move at its maximum rate of travel.
100% SPINDLE - ANS-An override key on the Haas control that sets the spindle back to
100% of the programmed value.
25% RAPID - ANS-An override key on the Haas control that limits rapid traverse to 25%
of maximum.
5% RAPID - ANS-An override key on the Haas control that limits rapid traverse to 5% of
maximum.
50% RAPID - ANS-An override key on the Haas control that limits rapid traverse to 50%
of maximum.
Alarm 176 - ANS-An alarm code on the Haas control that indicates the machine is
experiencing an overvoltage condition.
Alarm 177 - ANS-An alarm code on the Haas control that indicates the machine is
experiencing an overheating condition.
ALARM/MESGS - ANS-The display key on the Haas control that shows the current
alarms when pressed once and messages when pressed twice.
alpha keys - ANS-The area of the control keypad that allows an operator to enter letters
and special characters into the control.
, AUTO ALL AXES - ANS-In zero return mode, the key that returns and initializes all axes
to machine zero.
Auto Power Off Timer - ANS-Setting 1. A setting that indicates how many minutes of idle
time must lapse before the machine is automatically turned off.
AUX CLNT - ANS-A jog key that turns on the Through Spindle Coolant system when in
MDI mode. Pressing this key again shuts off the system.
block delete - ANS-A machine control that provides the option of skipping a
predetermined series of program blocks. A block delete allows the operator to run two
versions of the same program.
bracket - ANS-[ ]. Punctuation marks used to separate CNC program commands from
user comments.
CANCEL - ANS-A key on the Haas control that backspaces the cursor to delete the last
character entered or cancels any program block that is highlighted during a block edit.
CCW - ANS-An override key on the Haas control that starts the spindle in the
counterclockwise direction.
chip auger - ANS-A rotating shaft with a helical blade that removes chips from the
machine.
chip conveyor - ANS-A moveable belt that helps to remove chips from the machine.
CHIP FWD - ANS-A jog key that causes the chip auger to remove chips from the
machine.
CHIP REV - ANS-A jog key that causes the chip auger to move in the opposite
direction.
CHIP STOP - ANS-A jog key that causes the chip auger to stop.
CIRCLE-CIRCLE TANGENT calculator - ANS-A machining calculator that helps an
operator calculate points of intersection between two circles or points.
CIRCLE-LINE TANGENT calculator - ANS-A machining calculator that helps an
operator calculate points of intersection where a circle and a line meet as a tangent.
+10 FEEDRATE - ANS-An override key on the Haas control that increases the current
feed rate in 10% increments.
+10 SPINDLE - ANS-An override key on the Haas control that increases the current
spindle speed in 10% increments.
