Generate a Binder and reduce the Draw-In Reserve. The Draw-In Reserve defines the amount of material that is assumed to stay on the binder surface after drawing and, as such, the estimated blank outline will be affected by this parameter. 7. Generate an Addendum via Geometric method and apply the generation. 8. An error message occurs stating that Development fails at 1 flange (see next slide). Formability Analysis Exercise Formchk Indication of Critical Part Areas 6 7 8 PB I – R8 AutoForm Proprietary – Confidential 14 The error message shows, that one extruded hole could not be developed. 1. The reason for that is an embossed radius which is designed into the CAD-surface. An offset of 1.5mm is not possible for a radius of 1mm. 2. The development will not be further considered for Formcheck. When defining the process plan, the radius embossment has to be considered. 3. Go to the Develop Part tab and start the Formcheck analysis. 4. Increase the Outer Holding Condition to 0.2. This is a meaningful compromise between sufficient strain and little potential splits. Formability Analysis Exercise Formchk Indication of Critical Part Areas 3 4 1 PB I – R8 AutoForm Proprietary – Confidential 15 Basically there exists a critical part area, that shows a risk of splits even for a minor outer holding condition (0.2). The production of the part will not be feasible, so that the critical area has to be modified before developing the process in detail. For a first estimation of countermeasures and their effect the tools of the modify page are helpful. Formability Analysis Exercise Formchk Indication of Critical Part Areas Detail Detail : Critical part area PB I – R8 AutoForm Proprietary – Confidential 16 Formability Analysis As a first optimization step, a segmentation of the Outer Holding Condition will be performed to avoid potential splits. • Segmentation with Variable Holding Condition • Realistic representation of outer holding in an early phase. • Approximation of minimal blank size with an adjusted Outer Holding Condition value of 0.2 for the segmented holding condition. • Calculated forces of the Variable Holding Condition will be passed on to Plan-Stage. 1.

Tooling Cost and Piece Cost Calculation Exercise Tooling Piece Cost 1 2 PB I – R8 AutoForm Proprietary – Confidential 34 Piece Cost Tool and Maintenance Cost (1) • Part Material: Informational value set within Part / Material page regarding the material type. • Tooling Cost: Total cost of the dies (Engineering, CNC machining, Die making, Die try-out and the Tool material costs). When the tooling costs are available on Plan / Tooling, Total Tooling Cost value is taken automatically into Piece Cost, otherwise - manual input is necessary. • Maintenance Parameters: maximum possible number of strokes before necessary tool maintenance and percentage of the total tooling cost and defines the cost of one maintenance cycle (new gas springs, re- coating, die cleaning…). Input Values Essentials Piece Cost 1 PB I – R8 AutoForm Proprietary – Confidential 35 Piece Cost Blank Material Cost (2) • Utilization Factor presents the percentage of coil material that is used solely for the part production. This value is taken from the Blank stage; if no blank is available, default value of 70 % is set. • Coil Weight per Blank is estimated coil weight necessary for one blank. It is calculated based on the part weight and given Utilization Factor. Input Values Essentials Piece Cost 2 PB I – R8 AutoForm Proprietary – Confidential 36 Piece Cost Production Line Cost (3) • Press Hourly Cost is derived from the loaded press. • Press and Operation Downtime represents the percentage of downtime for press line service and maintenance • Used Stroke Rate is set in respect to Press Min and Max stroke rate • Strokes per Run has the default value of 5000. The default value can be changed directly in the GUI or within Process Plan Standard. • Forming Issues Downtime per Run is the estimated downtime due the forming issues during one run. Input Values Essentials Piece Cost 3 PB I – R8 AutoForm Proprietary – Confidential 37 Piece Cost Rework Cost (4) • Rework Cost per Part describes the cost for the necessary rework process(es) for one part. • Quality Rework Rate represents the percentage of parts of the Total Production Volume that needs to be reworked. The default value depends on the Robustness Level : an increasing Robustness Level leads to a decreasing rework rate. Input Values Essentials Piece Cost 4 PB I – R8 AutoForm Proprietary– Confidential 38 Piece Cost Shipping Cost (5) • Fixed Cost per Batch describes shipping cost that occurs for each batch of produced parts. • Variable Cost per Tonne contains the shipping cost for each tonne of produced parts. • Strokes per Batch represents the number of strokes that are "shipped" within one batch. Note that with one stroke there could be more than one part exiting the production line and therefore the number of strokes per batch can be smaller than the number of parts per batch. • Part Weight is calculated based on the part area and the material density. Taken from Part / Formcheck or Blank stages if available (considering thinning in these cases). Input Values Essentials Piece Cost 5 PB I – R8 AutoForm Proprietary – Confidential 39 1.
