Class Vocabulary
CANCEL		A key on the Haas control that backspaces the cursor to delete the last character entered, and cancels any program block that is highlighted during a block edit.
C-axis		A rotational axis that controls the rotation of the spindle for precise positioning of the workpiece. A C-axis is often required to effectively use live tooling.
cutter compensation		The use of G codes and radius offsets to compensate for the rounded tips of cutting inserts. If cutter compensation is used, the programmer creates a toolpath that follows the exact features of the part.
G41		A G code used with cutter compensation to shift the tool left of the direction of tool travel.
G42		A G code used with cutter compensation to shift the tool right of the direction of tool travel.
HANDLE		Part of the Haas control panel that moves machine components along the axes. The handle clicks in controlled, measured increments that an operator selects on the keypad.
HOME		A cursor key that moves a program quickly to its beginning or to the top of most displays.
homing		The process of sending the lathe's turret to its machine zero position.
inner diameter		An interior surface of a cylindrical workpiece or round hole.
input buffer		A temporary location on a computer that holds all incoming information before it continues to the control for processing.
job sheet		A document that includes all manufacturing specifications for a lot of parts.
lot		The number of similar parts made with a particular tooling setup.
machine zero		The position located at the farthest possible distance in a positive direction along the machine axes. This position is permanently set for each particular CNC machine.
offset		A numerical value stored in the CNC control that repositions machine components. Offsets are used to adjust for differences in tool geometry, part size, tool wear, etc.
OFSET		The display key on the Haas control that shows the various programmed offsets.
outer diameter		The exterior surface of a cylindrical or spherical workpiece.
program zero		The position that acts as the origin for the part program of a particular workpiece. This position is unique to each workpiece design, and it is selected by the part programmer.
programmable tailstock		A tailstock opposite the spindle that can be programmed to travel toward and away from the workpiece.
radius offset		An offset used on the lathe that slightly adjusts the tool to compensate for the rounded tip of an insert during contouring, chamfering, and other multi-axis operations.
STOP		An override key on the Haas control that stops the spindle.
stylus		The precision tip on the tool pre-setter that electronically records the turret position once a tool tip contacts its surface.
sub spindle		A secondary spindle opposite the main spindle that can be programmed to clamp a workpiece on its exposed end for additional machining on its back side.
taper offset		An offset used on the lathe that compensates for workpiece deflection. Each inch along the workpiece increases the compensation amount.
tip offset		An offset used on the lathe that indicates one of nine possible orientations for a particular tool. Tip offsets are used in conjunction with radius offsets.
tolerance		An unwanted but acceptable deviation from a given dimension. Tolerances indicate the allowable difference between a physical feature and its intended design.
tool geometry offset		An offset used on the lathe that accounts for variations in tool length along the X- and Z-axis. Each tool loaded in the turret requires its own geometry offset.
tool nose radius		The rounded tip on the cutting edge of a single-point tool. The greater the nose radius, the greater the degree of roundness at the tip.
tool pre-setter		A device on the lathe used to quickly determine tool geometry offsets on the X- and Z-axis. The tool tip contacts surfaces on the probe, which instantly records the turret position in the offset screen.
wear offset		An offset used on the lathe that slightly adjusts tool location to account for wear, deflection, and other variables that arise during machining.
work offset		An offset used to adjust the location of every tool loaded in the turret. On the lathe, the work offset changes the position of the turret in both the X- and Z-axis.
WRITE/ENTER		A key on the Haas control that acts as a general enter key.
X DIA MESUR		A key on the Haas lathe that automatically stores the X-axis position as a tool geometry offset for a tool that is properly touched off the workpiece surface. X DIA MESUR prompts the operator for a diameter measurement.
Z FACE MESUR		A key on the Haas lathe that automatically stores the Z-axis position as a tool geometry offset for a tool that is properly touched off the workpiece surface.
