Appendix B- Definitions
Auto Cycle – Automated workcell state where dispense cycles can be run.
Cycle Stop – Stopped workcell state where no manual or automated action occurs and the
workcell is at the standby position. Actions such as auto purge and solvent position moves
may occur at set intervals.
Database Backup File – A collection of projects, programs, tool configurations, and setup
parameters for a single machine, typically with the extension .bck or .abck.
NOTE: Prior to PathMaster 4.2 a database file could consist of multiple machines. This
functionality has been deprecated in version 4.2.
Database Transfer File – A collection of projects and programs used to transport machine-
level data from a source machine to a destination machine. A transfer file (.tfr) also
includes the workspace reference position, along with Z offsets for each tool. A transfer file
is similar to a database backup file, without the tool configuration and setup parameter
data.
Device – Any physical part processing device, such as a spray or dispense valve, a camera,
or a laser.
Dispense Path – A continuous motion profile. The tool is on (dispensing or spraying) during
the entire motion profile, also known as a path
.
Dot Drop Mode – A mode to teach the teach tool to run tool offset. A dot of material is
dispensed by the run tool and that dot is used as a reference to align the teach tool.
DMC – Language used to program the motion controller in the workcell.
End Effector – The dispense tool assembly. The end effector is moved by the axes.
Home Position – The (0, 0, 0, 0) location of the workspace. This position is determined by
the location of the home sensors. It is NOT the same as the
Standby Position.
Jog – One or more axes are commanded to move continuously at a specified speed
(measured in encoder counts per second) until commanded to stop.
Main Program File –The text file with the code to run the workcell in normal operation.
Needle Calibration – The procedure to find the position of the tool’s needle relative to the
expected position of the calibration sensors, the
Tooling Offset is then corrected to match
the found values. The difference is applied as a
Program Offset.
Needle Calibration Reference – Position where the crosshair on the needle calibration block
is centered below the system’s teach tool.
Offline Programming - A procedure to program path programs when not connected to the
workcell, known as FastPath™.

Offset Details – An information screen that shows the teach Tool Reference Position, Run
Tool Reference Position, Tooling Offset, and Profile Offset for the selected tool.
PathMaster® – Windows® Operating System based programming software. Used to create,
maintain and download program files for the workcell.
Profile Base – A physical device which has a plunger that is used as the Profile Z Reference
position for all run tools.
Profile Calibration – The process by which the Profile Offset is calculated for a given run
tool. This is accomplished by determining the difference of the Z position of the run tool
and the
Profile Tool at the Profile Z Reference.
Profile Offset – Distance between the Profile Z Reference and the tip of a given tool.
Profile Plunger Locate – The process by which the Profile Offset is calculated for a given
Profile Tool. This is accomplished by taking a Profile Tool reading at the surface of the
Profile Base’s plunger.
Profile Tool – A tool which may be used to determine the height of a desired dispense
surface in units of distance relative to a common surface.
Profile Z Reference – The common surface that is used in profile calculations. Usually, this
is the plunger of the
Profile Base.
Program – A collection (or series) of Dispense Paths and general commands.
Program Offset – Change in position that is applied to all programs in all projects. Program
offsets are generated by
Tool Offset Setup, Tool Change, and Needle Calibration.
Project – File consisting of up to 30 Programs.
Purge Position – The location in the workspace where the end effector moves to perform
all auto purge operations.
PVA –Precision Valve and Automation.
Run Tool Reference – The workspace position where the run tool is centered above the
system’s
Teach Tool Reference position.
Standby Position – The rest position for the end effector. The machine moves here after
homing and after each cycle. This position is usually located near the start point for the
program(s). It is not the same as the
Home Position.
Sensor Locate Sequence – Establish the spatial relationship between the Needle
Calibration Reference position and a repeatable location relative to the X and Y sensors.
Solvent Position – The location in the workspace where the end effector moves to idle in
solvent cups.

Teach Tool Reference – The workspace position where the teach tool is centered above a
crosshair or other identifying mark. This identifying mark will be used as a common location
for calculating
Tooling Offsets.
Terminal – A program used as a communication link between the controller and operator.
Tool – A virtualized instance of a Device, usually configured to a specific orientation.
Tool Change – Modifying the Run Tool Reference position relative to the Teach Tool
Reference to change the Tooling Offset. This function is generally used for adjusting a tool
position after a needle change, tool maintenance, etc.
Tooling Offset – Spatial relationship between the teach tool and the run tool.
Tool Offset Setup – Teaching the teach tool to run tool relationship (XYZW) in machine
parameters. This function is generally reserved for initial tool setup.
Workspace Reference – A fixed position in gantry space relative to the part fixturing. This
position is used as a source and destination machine for the purpose of transporting
machine programs. It may also be used to apply a global offset on all programs in all
projects.
