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

event

controller and tool status signal

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 the tool or controller

The HMI can be a web-based interface or a mobile interface.

IAM

Intelligent Application Module

module in the controller containing program data, 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.

mobile GUI

user interface to the controller through a browser window from a mobile device

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 the motor vehicle industry and in 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 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.

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 the controller through a 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

Are assigned to an entire controller and can be used by all virtual stations.
