    Abstract: In a method for determining at least part of a path (12) for connecting at least one starting point (14) to at least one finishing point (16) in a space (R) for at least one autonavigation of at least one movable component through the space on a machine (100), at least one model of the movable component and the machine is provided, information on the geometry is gathered, current positions are determined and these are brought into relation with one another to create a graph (10). An algorithm is used to calculate the path (12), collision-free autonavigation along the path (12) being carried out after a collision check has been performed. This assists the operator in adapting the machine cycle, while likewise bringing about an improvement in terms of the travel path, cycle time, reliability of the process, energy and wear.

    Abstract: Component manufacturing methods and systems and methods are provided for six degree of freedom control of a component prior to molding. A method involves obtaining measurement data from a measurement device indicative of a measured orientation of a component mounted to a surface of a tool associated with a molding assembly, determining an orientation adjustment based on a relationship between the measured orientation of the component and a reference orientation associated with the molding assembly, determining an actuation command for operating an actuation arrangement coupled to the tool based at least in part on the orientation adjustment, and providing the actuation command to the actuation arrangement to actuate the tool to rotate the surface in accordance with the orientation adjustment prior to forming a molding compound on an exposed surface of the component using the molding assembly.

    Abstract: A method for determining positions of a real moulding material front during a process to be carried out with a moulding machine, wherein



    a simulation progression (SV) of a variable characteristic of the process is calculated,
    positions of a simulated moulding material front are determined from the simulation,
    the real process is carried out, and at least one measurement progression (MV) of the at least one characteristic variable is measured directly or indirectly,
    a transformation is chosen, which has at least one parameter (ΔV, kp, Vunknown),
    the transformation is applied to the at least one simulation progression (SV), with the result that a transformed simulation progression (tSV) is formed, and
    a parameter value is determined for the parameter (ΔV, kp, Vunknown) such that a deviation between the measurement progression (MV) and the transformed simulation progression (tSV) is minimized according to a predetermined error measure or according to an operator input.

    Abstract: A moving-body monitoring device has a position detection unit that outputs positional information of a moving body, a proximity sensor that detects the moving body, a first storage unit that stores a position when the moving body having moved in a first direction is detected as first positional information, and stores a position when the moving body having moved in a second direction is detected as second positional information, and a calculation unit that calculates a fixed-point position of a detecting region of the proximity sensor during monitoring as fixed-point positional information based on the first and second positional information. The device also has a second storage unit that stores reference fixed-point positional information, and a monitoring unit that, when a deviation between the fixed-point and reference fixed-point positional information goes beyond a stipulated range, determines that a positional deviation amount of the moving body exceeds a tolerance.

    Abstract: A plasticizing device includes a plasticizing cylinder and a plasticizing screw arranged in the plasticizing cylinder. The plasticizing screw is rotatable about, and linearly movable along, a longitudinal axis. The plasticizing screw comprises a functioning section. A sensor is arranged in or on the plasticizing cylinder, and a distance to the surface of the functioning section of the plasticizing screw can be measured by the sensor. A detecting device can detect a type of the functioning section and/or an operating state of the functioning section, can detect a distance signal progression by a movement of the functioning section relative to the sensor, can compare the detected distance signal progression with a stored distance signal progression, and can issue a signal representing the type of functioning section and/or the operating state of the functioning section depending on a matching of the detected distance signal progression with a stored distance signal progression.
