Cel Following results have been achieved by the research work carried out within the AMANSIS project: - a methodology and prototype system for the provision of manufacturing information at part level based on - manufacturing-oriented classification of the part being currently designed with formerly produced parts while taking into account possible group technological aspects, - retrieved manufacturing models (including information on the required machine, tools, fixture configurations, NC-programs etc) related to the part models which have been classified as similar, - a methodology and prototype system for the provision of manufacturing information at feature level based on - a hybrid mechanism for processing of feature information consisting of a pre-defined feature database for standardised/recurrent design features and a feature recognition/learning tool with rulebase, - a geometrical reasoning mechanism for identification of manufacturing-influencing feature attributes, - a rule-based mechanism for automatic selection of appropriate cutting tools and machining parameters out of a commercial tool database according to the given feature type and the identified feature attribute values, - an NC-Analyzer extracting and structuring relevant geometrical and technological data from actually used NC-programs for detection of corresponding design features via coordinate transformation and comparison, for instantiation/updating of the tool database and for induction of NC-sequencing rules within - an NC-Machining Scheme Generator for building and determination of sets of NC-sequence types required for feature machining, - an NC-Macro Generator for rule-based forming, selection and instantiation of NC-macros required for feature machining and - a calculation tool computing the machining times according to the instantiated NC-macros With the results enlisted above an efficient decision support system enabling concurrent engineering to assess manufacturing feasibility, manufacturing costs, manufacturing times with respect to the due dates, and product quality to be expected during the design of new products has been made available.The aim of AMANIS is to create a fundamental approach for the provision of actual manufacturing information to the designer to improve future designs.Most of the cost of a product is fixed in the design process. This is especially true during design for production where design decisions have a considerable impact on production cost and time. For example, a shaft to collar connection can be designed as a positive connection (e.g. spring key connection) or as a pressed connection with friction contact. Both connections fulfil the function or torque transmission, but consideration has to be given to which connection is the cheaper to produce and which can best meet the delivery requirements. To make an informed decision the designer needs manufacturing information. This includes information about the machine availability and production interruptions, accuracy of machines, tools and fixtures, information about cost of quality, preparation time, manufacturing time and failure probability. However manufacturing information alone is not sufficient. It needs to be combined with information on products and shape elements to be meaningful to the designer. This information has to be collected, selected, prepared, structured and provided to the designer.This project will focus on a general approach to the information collection and preparation for the designer. The approach is limited to NC material removal processes like milling and tuming. In a modem computer-aided environment a great deal of data already exists. Shop floor control systems monitor data available from machine tools and controllers such as manufacturing times, failures or interrupts and production planning and control systems collect data related to orders. However, it is often found that the feedback of information to the design stage is insufficient.There is no general purpose tool or system available which provides the necessary information to the designer. The information has to be structured and prepared in such a way that it can be used to address the points raised above. That requires the use of advanced product model approaches including manufacturing features.
