The Total Cut Depth is the final depth, in Z, you want the tool to cut down to, regardless of the number of passes made. Router-CIM uses this number to calculate the Z axis moves for the Total Depth to cut into the material. If the Depth/Pass field has a number smaller than this, Router-CIM calculates the number of passes necessary to reach this depth. You may enable Router-CIM to calculate the depth automatically for you based on the thickness you give a part. To do this place "A" in the Total Cut Depth field, and give you part thickness. Router-CIM will use that value for the Z depth. Remember to give your part negative thickness!
**Note**
Also, when you give your parts negative thickness, you can use a forward slash (/) followed by a negative value (/-.01 for example) in this field. Router-CIM will take the negative part thickness (-.75 for example), and the negative value following the slash and calculate the Total Cut Depth. In this case the part would be cut to -.76.
The following section on Material Thickness Compensation can directly affect Total Depth.
