Abstract
A method and system for determining a set of desired machine specifications. The method and system includes inputting a set of data to a processor, the data including information relevant to a machine, a machine tool, and a machined part, determining a required set of specifications of the machine as a function of the data, and outputting the required set of specifications to a user.

A computer-based method, for determining a set of desired machine specifications, including the steps of:
- inputting a set of data to a processor, the data including information relevant to a machine, at least one machine tool, and at least one machined part, wherein inputting the set of data includes the steps of;
- inputting a desired machine configuration;
- inputting information relevant to a work volume of the machine;
- inputting information relevant to a maximum deviation of the machine tool from an intended path;
- inputting a quality index Cp of the machine, the quality index being a function of a percent contribution of the machine to a quality of the machined part;
- inputting information relevant to at least one feature of the machined part;
- inputting information relevant to a size of the machine tool;
- and
- inputting information defining at least one axis for the machine tool to travel to make the at least one feature of the machined part;
- determining a required set of specifications of the machine as a function of the and outputting the required set of specifications to a user.
A method for determining a set of desired machine specifications, including the steps of:
- inputting information to a processor, the information being relevant to a machine, a machine tool, and a machined part, including information relevant to allowable tolerances of the machined part;
- determining a required set of specifications of the machine as a function of the information, including allowable machine error specifications;
- and
- outputting the required set of specifications to a user.
A method for determining a set of desired machine specifications by a processor, including the steps of:
- receiving information relevant to a machine, a machine tool, and a machined part, the information relevant to the machined part including at least one machined part feature;
- determining a set of worst case points for each of the at least one machined part feature;
- determining a set of potential error terms corresponding to the set of worst case points, the potential error terms being a function of errors associated with the machine and the machine tool;
- determining a set of geometric dimensions and tolerances of each of the at least one machined part feature as a function of the potential error terms;
- and
- determining a resultant set of machine specifications as a function of the geometric dimensions and tolerances.
A system for determining a set of desired machine specifications, comprising:
- an input module for inputting information to a processor, the information being relevant to a machine, a machine tool, and a machined part, including information relevant to allowable tolerances of the machined part;
- a processing module for determining a required set of specifications of the machine as a function of the information, including machine error specifications;
- and
- an output module for outputting the required set of specifications to a user.
