To Document the Part Machining Process Plan
In documenting the part machining process plan work flow, the user wants to:
1. Document the process planning steps.
2. After defining a manufacturing process plan step, the user needs to document the process planning step in a company accepted format. There are five classes of process planning steps which require specific documentation:
Material removal—which includes typical manufacturing steps such as mill, turn, drill, bore, tap, and so on.
Fixturing—which includes a typical setup drawing; for example, place part A into fixture B.
Manufacturing model—which includes assembly of material or the creation of additional workpieces.
Non-manufacturing—which includes inspection, packing, and deburring.
Non-material removal—which includes shrinkage and plating. The documentation is similar to the material removal step except no geometry simulation is performed; that is, the results of these steps are not reflected in part geometry.
3. Simplify the representation of a part in all non-machined areas.
In some cases, the user wants to simplify the display of any part geometry which is non-critical to the particular machining step in order to simplify the manufacturing model representation.
4. Document the material removal process.
The user needs to document the material removal process including minimum sufficient dimensioning, tool and holder information, along with any necessary machining instructions.
5. Create drawing views or report tables for each machining process. The end products of the process planning procedure include:
The tool selection
The holder
The fixture list which is cross-referenced to the process plan step
The setup drawing which contains a simplified, representative assembly of the workpiece and fixture assembly
The process plan drawing which contains the workpiece and the necessary dimensions, tolerances, and instructions to produce that material removal step
6. Create and dimension auxiliary views.
For some of the drawings, the user may need to create and dimension additional breakout sections or auxiliary views as appropriate.
