Title: IMPROVEMENTS IN OR RELATING TO THE CONTROL OF A CHAIN OF MACHINES, INCLUDING AN ADDITIVE MANUFACTURING MACHINE, IN THE MANUFACTURE OF A WORKPIECE
Abstract:
This invention concerns apparatus for generating instructions for machines of a manufacturing chain (101) used to manufacture a workpiece. The apparatus comprising a processor (131) arranged to receive a model based definition (MBD) of a workpiece (218) including geometric dimensions and tolerances; receive inputs setting an additive build design for building the workpiece (218) based upon the geometric dimensions; generate additive instructions for an additive manufacturing machine (103a, 103b, 103c) of the manufacturing chain (101) based upon the additive build design; determine a prospective intermediate workpiece product expected from an additive build in accordance with the additive build design; determine differences between the prospective intermediate workpiece product and the model based definition of the workpiece; and generate further instructions for at least one further machine (104, 105 to 110) of the manufacturing chain (101) based upon the differences.
