Method of controlling a machine for the manufacture of products, in particular for controlling an injection molding machine

A method for controlling an injection molding machine comprising the steps of:

• preselecting a number of at least two quality parameters, which are essential for a product to be produced;
• preselecting a number of setting parameters of the machine, said quality parameters of the product being dependent on said setting parameters of the machine;
• determining and storing characteristic data arrays in a learning cycle, which characteristic data arrays reflect the dependencies between said quality parameters and said setting parameters;
• inputting reference values or reference value ranges into a control unit for each preselected quality parameter;
• ascertaining for each quality parameter by the control unit a set of all setting parameter combinations, for which the respective quality parameter corresponds to the corresponding input reference value or lies in the input reference value range;
• and
• determining the intersection of said sets in order to obtain to obtain those combinations of setting parameters for which simultaneously all preselected quality parameters correspond to the input reference values or lie in the input reference value range;
• the step of determining and storing characteristic data arrays in a learning cycle comprising the substeps of setting each preselected setting parameter to at least three different values;
• producing one or more products at each value of each setting parameter;
• and
• determining and inputting the value of each quality parameter of each of the produced products.

A method for controlling an injection molding machine comprising the steps of:

• preselecting a number of at least two quality parameters, which are essential for a product to be produced;
• preselecting a number of setting parameters of the machine by making use of a table which numerically evaluates the basic influenceability of quality parameters by setting parameters, wherein those setting parameters are selected in which the sum of all evaluation numbers exceeds a predetermined value;
• determining and storing characteristic data arrays in a learning cycle, which characteristic data arrays reflect the dependencies between the quality parameters and the setting parameters;
• inputting reference values or reference value ranges into a control unit for each preselected quality parameter;
• and
• ascertaining by the control unit a set of setting parameters in which simultaneously all preselected quality parameters correspond to the input reference values or lie in the input reference value range.
