This clause specifies the information required for model based integrated manufacturing, including information requirements defined by the ISO 14649 data model for computerized numerical controllers.
The information requirements are specified as a set of units of functionality, application objects, and application assertions. These assertions pertain to individual application objects and to relationships between application objects. The information requirements are defined using the terminology of the subject area of this application protocol.
NOTE 1 A graphical representation of the information requirements is given in Annex G.
NOTE 2 The information requirements correspond to those of the activities identified as being within the scope of this application protocol in Annex F.
NOTE 3 The mapping specification given in clause 5.1 defines how the integrated resources and application interpreted constructs are used to meet the information requirements of this application protocol.
This subclause specifies the units of functionality for the model based integrated manufacturing application protocol. This document specifies the following units of functionality:
The units of functionality and a description of the functions that each UoF supports are given below. The application objects included in the UoFs are defined in 4.3, ISO 14649, or ISO 10303 application modules as indicated below.
The measure UoF specifies the representation of physical quantities by its value and its unit, along with the representation of allowable variation in that quantity.
NOTE 1 The previous edition of this document referenced application object definitions from ISO 14649-10, extended the definitions in several places, and defined mappings into the integrated definitions. These have been replaced by a reference to equivalent application object definitions and mappings defined by the documents listed below.
The names of some application objects are changed from the previous edition. The former Area_measure application object is now Area_data_element; Length_measure is now Length_data_element; Mass_measure is now Mass_data_element; Plane_angle_measure is now Angle_data_element; Pressure_measure is now Pressure_data_element; Rot_speed_measure is now Frequency_data_element; Speed_measure is now Velocity_data_element; Time_measure is now Duration; Volume_measure is now Volume_data_element.
The Value_with_tolerance and Toleranced_length_measure defined by the previous edition have been replaced by one of three different application objects depending on their use. Value_with_unit when no tolerance limits are applied, Value_with_tolerances for values with a plus/minus limit, and Qualified_numerical_item_with_unit for other limits. Limit_qualifier, Limits_and_fits, and Plus_minus_value are now the value_qualifier of Qualified_numerical_item_with_unit, or Dimension_value_with_limitation when used with dimensions.
NOTE 2 As defined in ISO 14649-10, these measurements do not explicitly specify a unit. Instead, a default unit is defined for each quantity (mm for length, degrees for angles, etc). In addition, only length parameters could be qualified with a tolerance. The definitions used by this document allow units to be explicitly specified, allow tolerance qualification for any of the measure types, and adds a maximum/minimum Limit_qualifier to the types of qualifications available.

A Machine_axis_constraint identifies the range of motion that a machine axis may traverse.
NOTE 1 It is advisable to avoid use of this information since it is machine dependent. To execute an operation or toolpath, an NC controller converts curves in space into specific axis motions.

The machine_axis_constraint mechanism allows additional guidance to be provided to the controller by restricting the motion of one or more axes to be considered as part of the solution.
EXAMPLE When a rotary C table is mounted on a rotary B table, there may be two combinations of C and B angles that give the same tool axis direction. Also, when drilling on a machine with redundant (not necessarily parallel) linear axes, such as a machine with a movable quill (W axis), either the W or other axes could be used to advance the drill.

The its_id specifies the string identifier of the Toolpath. The its_id may not be specified for a particular Toolpath.
The its_broadcast specifies a Broadcast object that describes the conditions and contents of messages that are to be issued about the toolpath. The Broadcast object shall be evaluated every time process execution encounters the toolpath.

The Toolpath_list application object shall be as defined by ISO 14649-10. This document adds the following information requirements.
The data associated with a Toolpath_list are the following:

The its_list set shall be as defined by ISO 14649-10 to be of type Toolpath, but this document relaxes this requirement to also allow NC_function.
NOTE This relaxation allows the use of an NC function between toolpaths without breaking a process into two separate operations and workingsteps.
The Toolpath_speed application object shall be as defined by ISO 14649-10. This document adds the following information requirements.
The data associated with a Toolpath_speed are the following:
NOTE The ISO 14649 EXPRESS description for Toolpath_speed, as adapted by this document, is shown below. Refer to ISO 14649-10 for the original definition and explanation of usage.
ENTITY Toolpath_speed; speed: bounded_curve; -- RELAXED BY 10303-238 WHERE WR1: speed\geometric_representation_item.dim = 1; END_ENTITY;
The speed parameter shall be as defined by ISO 14649-10 to be of type b_spline_curve, but this document relaxes this requirement so that the speed shall be of the more general type bounded_curve. All constraints on the parameterisation of the curve defined by ISO 14649-10 shall remain in effect. See Matching curve parameterization for additional discussion on the curve parameterization requirements.
NOTE This relaxation allows the use of simpler polyline speed curves already present in sources such as existing APT/CL data without forcing reparameterisation of the data into a more complicated B-spline curve. Because the parameterisation contstraints remain in effect, the speed curve for a polyline basiccurve would be a polyline with the same distribution of points.
A Touch_probe is a type of Machining_tool that meets the information requirements defined for Touch_probe by ISO 14649-10. This document adds the following information requirements.
The data associated with a Touch_probe are the following:

The data associated with a User_defined_milling_tool are the following:
NOTE 2 The EXPRESS description for the User_defined_milling_tool application object is shown below.
ENTITY User_defined_milling_tool SUBTYPE OF (Milling_machine_cutting_tool); corner_radius: OPTIONAL Length_data_element; corner_radius_center_horizontal: OPTIONAL Length_data_element; corner_radius_center_vertical: OPTIONAL Length_data_element; description: OPTIONAL text; taper_angle: OPTIONAL Angle_data_element; tip_outer_angle: OPTIONAL Angle_data_element; END_ENTITY;
The corner_radius specifies the radius of the corner circle which describes the transition between the upper and lower line segments of the tool profile as shown in Figure 22.

The Workingstep application object shall be as defined by ISO 14649-10. This document adds the following information requirements.
The data associated with a Workpiece are the following:
NOTE The ISO 14649 EXPRESS description for Workingstep, as modified by this document, is shown below. Refer to ISO 14649-10 for the complete definition and explanation of usage.
ENTITY Workingstep ABSTRACT SUPERTYPE SUBTYPE OF (Executable); its_secplane : elementary_surface; final_features: OPTIONAL SET [0:?] OF Manufacturing_feature; -- ADDED BY 10303-238 -- 10303-238: consolidate its_operation into supertype for -- consistent handling across technologies its_operation: Operation; toolpath_orientation: OPTIONAL Axis_placement_3d; -- ADDED BY 10303-238 END_ENTITY;
The final_features specifies a set of zero or more Manufacturing_feature objects visible on the final form of the workpiece that the workingstep contributes to. If a workingstep calls out a process-specific feature consumed or obscured by further activities in a process, final_features may be used for traceability to features on the final form of the workpiece. It is not required that final_features be specified for a particular Workingstep. See Workingstep to Manufacturing_feature (as final_features) for the application assertion. See Features describing process or final form for additional discussion on the use of this attribute.
NOTE Consider the flow of data through the design and manufacture of a part. The features on the final part are usually the input to process planning, possibly described as an ISO 10303-224 data set. The output of macro process-planning, possibly described as an ISO 10303-240 data set, will include these features as well as intermediate features related to a particular process. This document describes the micro process-plan and is concerned with the features associated with a particular process, but having the ability to associate a process step with the ultimate feature on the final part allows us to preserve information flowing down from the larger process-plan. This will be of benefit to related downstream tasks, such as inspection, which could use the tracability to pinpoint critical areas of interest in the micro and macro process-plans.
EXAMPLE A workingstep drills a hole which is later used as the entry point for a pocketing operation. The hole is consumed by pocketing operation and not visible on the final form of the workpiece. The final_features of the drilling workingstep may reference the pocket to indicate participation in the creation of that feature.
The its_operation specifies an Operation object that describes the action performed by the Workingstep. See Workingstep to Operation for the application assertion.
NOTE The ISO 14649 model originally defined separate its_operation parameters on the Workingstep subtypes. These have been brought into the supertype for conceptual consistency as the defining characteristic of a workingstep.
The toolpath_orientation specifies the placement of the set of toolpaths given by the its_operation its_toolpath parameter. The toolpath_orientation may not be specified for a particular Workingstep. If the toolpath_orientation is not specified, the toolpaths shall assume an origin of (0,0,0) and axis directions X=(1,0,0) Y=(0,1,0) and Z=(0,0,1).
NOTE To reuse the toolpaths of an operation in a different location, ISO 14649 uses the origin from different features associated with the operation through a workingstep. This technique is not practical in this document because of feature harmonization constraints, since features often come from design and planning with origins that were convenient for the designer.
