METHOD FOR HUMAN-MACHINE COMMUNICATION BY MEANS OF A HUMAN-MACHINE INTERFACE AND DEVICE FOR THIS PURPOSE
The invention relates to a method for human-machine communication during the operation of a machine (10), as well as a machine (10). An input (E) is detected via a human-machine interface (22) or another input point and transferred to an assignment block (30). In the assignment block (30), it is checked whether a reaction matching the input (E) can be assigned in the form of an output sequence (31). To this end, for example, a comparison can be made between patterns. If an output sequence can be assigned, same is executed and, depending on the output sequence (31), e.g. information (B) is output and/or at least one control signal (S) is generated for an actuatable component of the machine (10). If an assignment of an output sequence (31) is not possible, a generation sequence (38) is started. First a new output sequence (31n) is generated and then checked to ascertain whether there is a matching template (41) for same in a template database (40). If so, the value of a counter (42) assigned to this template (41) is increased by one. If there is no matching template (41), a new template (41) is generated based on the new output sequence (31n) and stored in the template database (40). Based on the templates (41) and the value of the counter (42) for each template (41), a requirement for adjustment of the machine or the machine controller or the human-machine interface (22) can be detected and rectified. This requirement is automatically determined via and during the operation of the machine (10).

PRESS AND METHOD FOR COLD WORKING A BLANK TO FORM A HOLLOW BODY
The invention relates to a press (10) and to a method for producing a hollow body (14) from a blank (13). The press (10) comprises a ram (11) which supports a ram tool (12) and can be moved in a working direction (A) along a longitudinal axis (L). The ram tool (12) works together with a die tool (26) in order to work the blank (13) to form the hollow body (14). The working is carried out as cold working, for example as ironing. The ram (11) is supported by a guide assembly (19) having one or more bearings (20) so as to be movable in the working direction (A) and is moved by means of a drive (18). If uneven heating of the ram (11) leads to deformations that mean that the ram (11) is no longer exactly symmetrically aligned with the longitudinal axis (L), accelerations of the ram (11) may cause vibrations which lead to deviations in the wall thickness of the hollow body (14) produced. In order to prevent this, according to the invention the ram (11) is produced from an iron-alloy and preferably an iron-nickel alloy which has a thermal expansion coefficient (a) at most of 3.0 x 10-6 K.
istsollistmaxistmaxmax) (figure 9). The oscillating movement of the rotor (17) consequently does not cause the actual stroke position of the ram (12) to change, but instead merely causes the value of the deflection (a) to vary during the reciprocating operation (PB). Thus, the reciprocating operation (PB) does not bring about an undesirable change in the position of the ram (12), and yet an overloading of the drive (13) or of the drive motor (14) and of the frequency converter (29) is avoided.
