3.1

press

machine tool designed or intended to transmit energy to a tool/punch for the purpose of the working (e.g. forming or shaping) of metal or other material worked in the same way between the tools

3.2

hydraulic press

hydraulic servo press

press (3.1) designed or intended to transmit energy by linear movement between closing tools by hydraulic means

[SOURCE:ISO 16092-1:2017, 3.1.4, modified — The Note 1 to entry has been deleted.]

3.3

mechanical press

press (3.1) designed or intended to transmit energy from a prime mover to a tool/punch by mechanical means using a clutch mechanism which transmits torque to impart motion of the flywheel to the slide

[SOURCE:ISO 16092-1:2017, 3.1.2, modified — The Note 1 to entry has been deleted.]

3.4

mechanical servo press

press (3.1) designed or intended to transmit energy to a tool/punch by mechanical means using a servo drive mechanism without clutch mechanism to generate torque to impart motion to the slide

[SOURCE:ISO 16092-1:2017, 3.1.3, modified — The Note 1 to entry has been deleted.]

3.5

double action press

press (3.1) containing a die cushion for deep drawing purposes

3.6

press brake

machine tool designed or intended to transmit energy to the moving part of the tools by hydraulic means and/or mechanical means with or without using a servo drive mechanism, principally for the purpose of bending between narrow forming tools along straight lines

3.7

pipe bender

machine tool designed or intended to transmit energy to constrain or strain to tension by bending pipes

3.8

turret punch press

type of press (3.1) used to cut holes in material, which can be small and manually operated holding one simple die set, or very large and NC controlled with a single or multi-station turret holding a much larger and complex die set

3.9

laser processing machine tool

machine tool in which (an) embedded laser(s) provide(s) sufficient energy/power to melt, evaporate, or cause a phase transition in at least a part of the workpiece, and which has the functional and safety completeness to be ready-to-use

[SOURCE:ISO 11553-1:2005, 3.2 modified —"machine" is substituted by"machine tool"]

3.10

slide/ram

main reciprocating press (3.1) member which holds the tool/punch

[SOURCE:ISO 16092-1:2017, 3.2.12]

3.11

beam

main reciprocating press brake member which normally holds the punch on a down-stroking press brake, and which normally holds the die on an up-stroking press brake

[SOURCE:EN 12622:2009, 3.1.1]

3.12

die cushion

accessory for a die which accumulates and releases, or absorbs, force as required in some press (3.1) operations

[SOURCE:ISO 16092-1:2017, 3.2.6]

3.13

tool/die

device for imparting a desired shape, form, or finish to a material

3.14

moving bolster

movable plate carrying the tools or dies (3.13) and moving during tool change

3.15

automation system

system for loading and/or unloading of workpieces by highly automatic means, reducing human process intervention to a minimum

3.16

spacer

device to hold a space open [e.g. between slide and moving bolster or between slide and die cushion (3.12) ] on hydraulic or mechanical presses

3.17

regenerative circuit

shaft side of a double action cylinder connected to the head side, so that fluid exiting the shaft side is added to the fluid entering the head side

3.18

total power

power applied to a machine tool component at the feeding point of the machine tool component

3.19

power loss

loss of power applied to a machine tool component, mostly transferred to heat (e.g. due to friction or throttle losses)

3.20

inverter system

system generating variable frequency to energize electric motors for variable speed, consisting of line reactor and/or line filter and the inverter itself

3.21

dead centre
