# 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.
