A method for controlling a machine for processing plastics and other plasticisable materials such as powder and/or ceramic materials, wherein the machine comprises - a mould opening and closing unit , for opening and closing an injection mould comprising at least one mould cavity for manufacturing a moulding that corresponds to the shape of the mould cavity , - an injection moulding unit having devices for plasticising and for injecting the plasticisable material into the mould cavity , - a machine controller that is in communication with an expert knowledge unit and where necessary is configured to be interactively influenced by the operating person, wherein the method comprises the steps of: - providing information, on the geometry of the moulding and/or the mould cavity that receives the moulding, to the machine controller , - providing information on the sprue geometry to the machine controller , - calculating at least one step-by-step volume growth profile of the moulding in the direction of filling the mould cavity , taking into account the geometric information, wherein the volume growth profile of the moulding is calculated layer by layer, beginning from at least one sprue point, wherein a particular distance (Δs) covered by a conveying device, or a particular volume (ΔV), is associated with each layer, - wherein the calculation of the at least one step-by-step volume growth profile of the moulding is performed before a first injection procedure for manufacture of a moulding is carried out, - wherein the volume growth profile is calculated taking into account at least one of the items of information in respect of the total injection volume or the thickest and thinnest wall thickness of the moulding or the wall thickness ratios or flow path ratios, wherein this information is preferably to be found in the expert knowledge unit, and - wherein at least one injection procedure is calculated, taking into account the step-by-step volume growth profile and on the assumption of a material front that flows at constant speed. - a mould opening and closing unit , for opening and closing an injection mould comprising at least one mould cavity for manufacturing a moulding that corresponds to the shape of the mould cavity , - an injection moulding unit having devices for plasticising and for injecting the plasticisable material into the mould cavity , - a machine controller that is in communication with an expert knowledge unit and where necessary is configured to be interactively influenced by the operating person, wherein the method comprises the steps of: - providing information, on the geometry of the moulding and/or the mould cavity that receives the moulding, to the machine controller , - providing information on the sprue geometry to the machine controller , - calculating at least one step-by-step volume growth profile of the moulding in the direction of filling the mould cavity , taking into account the geometric information, wherein the volume growth profile of the moulding is calculated layer by layer, beginning from at least one sprue point, wherein a particular distance (Δs) covered by a conveying device, or a particular volume (ΔV), is associated with each layer, - wherein the calculation of the at least one step-by-step volume growth profile of the moulding is performed before a first injection procedure for manufacture of a moulding is carried out, - wherein the volume growth profile is calculated taking into account at least one of the items of information in respect of the total injection volume or the thickest and thinnest wall thickness of the moulding or the wall thickness ratios or flow path ratios, wherein this information is preferably to be found in the expert knowledge unit, and - wherein at least one injection procedure is calculated, taking into account the step-by-step volume growth profile and on the assumption of a material front that flows at constant speed. <EOS>
