Taking Maximum Wear Cutting Condition into Account

You have to validate the ISO code in conditions where the tool is worn and leaves more material than expected, this leads to collisions. This is solved by taking the Maximum Wear Condition into account.

The stages in this procedure are as follows:

Define the Wear Condition of the Tool

You can define maximum wear parameters when defining drill tools, end mill tools, face mill tools, conical mill tools, and T-Slotters.

  1. While defining one of the tools listed above, click More and go to the Geometry tab.
    1. Select the Maximum Wear Condition check box.
    2. Define the three parameters linked to Maximum wear condition: Radius offset (Cutting), Radius offset (Shank), Length offset.

      By default, these parameters are set to 0.

      The Maximum Wear Condition with a length offset means the tool is shortened (that is tool gauge is reduced). The reference point of the tool is computed starting from the Base axis with a Z offset corresponding to the Length offset value

  2. Click OK.
    The tool is created in the Manufacturing Cell, with Default XXX representations and Worn XXX representations.

    An alternative is to create an user representation of the worn tool. Create the 3D Part with the requested geometry definition,

    • The position of the representation must respect the alignment with the length offset.
    • The shapes must be coherent regarding the radial offset.
    • The coherence of the parameters, user representation and position of the representation are under your responsibility.

    Attach it to the tool. See Management Representations.In this user representation, set State to Worn and Rotary to Yes.

Define the Cutting Tool Condition for the Simulation

You can choose the cutting tool condition used for simulation.

  1. Select Me > Preferences > App Preferences > Simulation > Machining > NC Machining Apps Common Services > Simulation.
  2. Do the following:
    1. Make sure the Enable Material Removal Computation During Simulation check box is selected.
    2. Select the Cutting Tool Condition for the simulation.
    • If you select Nominal, the simulation is computed with the nominal tool, example, with the Default XXX representations or the user representation of the nominal tool, if it exists.
    • If you select Maximum Wear, the simulation is computed with the worn tool, example, with the Worn XXXrepresentations or the user representation of the worn tool, if it exists.
      Note: Priority is given to the user representations, when they exist.
    • The Cutting Tool Condition selected applies to all the tools of the simulated program. If no Maximum Wear Condition is defined for a tool, the simulation is done with the nominal condition.
