Eeva Järvenpää Eeva Järvenpää ProductModel ontology is defining product requirements. It defines the structure of product; its associations and liaisons; process requirements in terms of capabilities, and their parameters.

These can be for example parameters or other metadata. 1 1 Process is a subclass of Activity. Process can have multiple sub-processes, where the order of processes is defined by dependencies (process 1 has to be completed before process 2). 1 1 Part is a single entity in the product. One part can also be a product. This class contains information about protrusion in an object Coordinate class represents the position coordinates of a entity. Coordinate can be world coordinate, tool point coordinate or frame position coordinate depending on the feature itself. 1 1 1 Setup class is reserved for activities relating to setting up machines. These are activities which can not be regarded as processes from the product point of view, but which need to be done in order to the process to take place. 1 1 TODO: This class is currently under construction. Geometric features relating to the product. This class is intended to store information on such geometric features, which affect to the required capabilities. This class contains details about fixation, which is done by using certain kind of fixing elements. This is used to indicate how many similar fixing elements (e.g. screws) belong to certain assembly. 1 1 1 This class is used to save information of screws (or bolts) in the product 1 1 1 1 1 SurfaceTreatment class represents the surface treatment of a product. It can be for example plastic coating, filming of the plastic... This class is used to save information of nuts in the product 1 1 1 Activity class is for storing the processes and their occurances. 1 1 Product is any manufactured, handled or processed part or combination of physical parts. It is the final product from the modeller's perspective. It may be a single assembly or part. 2 Assembly class is for any manufactured, handled or processed combination of physical parts. Assembly must include at least two parts or other assemblies. 1 1 1 1 This class is used to save information about rivets used in the product This class is used to save information about the nails in the product . 1 1 1 1 Orientation class is for presenting the orientation of a feature. It is presented in quaternion. 1 1 ProductElement class is the super class for products, assemblies and parts. 1 1 1 This class is used to model the shallow cylinder shapes. Shape and size of an object . TODO: How to eliminate the need to model each similar fixing part as a separate instance? Or should they be modelled separately? Each needs to be assembled anyway, so they affect to the process. 1 This class contains different fixing parts that are part of the product. Tolerance class includes the tolerance values a face can posses. This class is under construction. 1 1 1 This class contains information about the hole in an object. 1 1 1 Material class is used to store specific material instances. 1 1 1 2 2 1 A process may need some setup activities, before it can take place. Activity requires one or many process capabilities. This property is used to make the reference to the correct level on the process taxonomy, where the required parameters are also defined. This property defines the raw material of the given part. This property is used to relate a geometric feature to certain object. Activities performed on a product element. Product element may be part, assembly or complete product. This property is used to model the shape and size of an object. Refers to the specific fixation. Defines the occurance order of the activities. An activity can have multiple dependencies, e.g. activities 1, 2, 3 and 4 must be completed before the activity 5 can occur. This property specifies the features that the entity has. Feature may have multiple sub-features. <p style="margin-top: 0"> This property is used </p> Can include one or many instances from the class Part or Assembly. This property indicates the features or products where the non-geometric features are referring. Unit: Millimeters (mm) Unit: Millimeter (mm) Depth of the hole to be drilled.
