Terms and Definitions

Term	Synonym	Definition	Note
batch		multiple tightening using the same tightening program and socket
batch sequence	sequence	multiple tightening using a combination of different tightening programs and sockets
controller GUI		user interface at controller buttons or touch screen
event		controller and tool status signals
final angle		actual measured angle value at the end of the tightening cycle
final torque		actual measured torque value at the end of the tightening cycle
GUI		user interface made up of interactive graphical elements such as windows, icons and symbols on a display
HMI	Human Machine Interface	user interface to tool or controller	The HMI can be a computer web-based interface or controller touch screen.
IAM	Intelligent Application Module	removable module in controller containing program, configuration parameters and tightening results
line structure		sorting and grouping controllers in structures, folders or sub-folders in ToolsTalk	The line structure is a method for improving the visibility of a large group of controllers in a structured manner.
post view torque		function for monitoring and detecting torque maximum and minimum values before rundown is complete	One purpose of post view torque is the use of a self-locking nut.
Tightening program	Parameter set	configuration of parameters and values to control and monitor a single tightening action, and to store the tightening result
push		transfer of data saved in ToolsTalk to the controller memory
QIF	Quality Integrated Fastening	fully integrated line of nutrunners, controllers, accessories and process monitoring tools to guarantee high quality and traceability of tightening in industrial assembly systems	QIF was developed at Atlas Copco and is preferably used in motor vehicle industry and other assembly situations where many joints are critical. The QIF concept also includes process monitoring and documentation.
QIF accessory		accessory for operator communication and guidance used in QIF	Accessory products used for communication between system and operator. For example: scanner, operator panel, stacklight and socket selector. The communication provides improved quality and traceability in the assembly process.
quick step		tightening strategy	A tightening strategy to reduce the joint’s preload scatter by combining an initial step with a given speed and torque and then reducing the speed in the final step.
Re-hit detection		detection of re-tightening of an already tightened joint
rotate		tightening strategy which rotates the tool head.	Rotate is mainly used for test or demonstration purposes.
rundown complete		end of the rundown step, when the screw head is in contact with the surface and the tightening step begins
rundown step		step when a bolt enters the thread until the bolt head touches the surface
snug		screw or bolt is approximately finger-tight to the surface
socket selector		QIF accessory, consisting of a socket tray with lamps, that can be used to guide an operator to the correct socket
soft start		start tightening at slow speed during a specified rotation angle	The function helps the bolt to enter the thread in a well controlled way and may prevent unwanted ergonomic tool movement when the trigger is pressed.
stacklight		QIF accessory, which handles the communication between operator and controller through digital signals like lamps, buttons, switches and buzzer
target		desired result of a tightening	The target is expressed in torque or angle.
target angle		desired angle value at the end of the tightening cycle, measured from a reference point
target torque		desired torque value at the end of the tightening cycle
three step		tightening strategy	A tightening strategy to reduce the joint’s preload scatter and relaxation effects with an initial step with a given speed and torque followed by a short loosening step before the final tightening at reduced speed.
tightening step		step from when a bolt head has reached the surface until the tightening has reached the desired target torque or target angle
tightening strategy		algorithm which continuously controls and monitors the tightening process	The user can select a strategy optimized for the joint and program certain parameters.
TurboTight		tightening strategy	A tightening strategy based on the tool’s maximum speed to perform fast and ergonomic tightening. The strategy requires only a target torque value to be set.
two step		tightening strategy	A tightening strategy to reduce the joint’s preload scatter and relaxation effects with an initial step with a given speed and torque, followed by a short-term stop, before the final tightening at reduced speed.
web GUI		user interface to controller through web browser window from a remote computer
virtual station	virtual controller	software abstraction of a physical controller to behave like multiple controllers	A controller can have only one cable tool connected to it, but several wireless tools. Each tool is connected to its own virtual station.
Virtual station type		License containing a bundle of controller features.	This license is required for running a virtual station.
Virtual station feature		License for individual features.	Can be used to complement Virtual station type licenses.
Controller feature		License for controller-wide features, such as Soft PLC and synchronized tightening.	Are assigned to an entire controller and can be used by all virtual stations.
