Hi, sorry for the naive questions. I have a new CNC mill, some basic Rhino skills and have just in the last week begun practising making toolpaths and cutting small shapes with Madcam. My main aim at the moment is to be able to cut model aircraft wing mould shapes - female (negatives) directly into board.
I want to face the mould parting line (flanges) flat, so I want to start with 0.2mm of stock material excess above the model. I mark a spot on the stock outside the cutting area as the zero, where I touch down to reset zero at each tool change.
Should I position the model with the parting line at 0.2mm below the stock box, with the top of the stock box at zero??
Or leave the model at zero, let the stock box selector set the top of the box to the parting line, and tell Mach3 that the zero position is 0.2 not zero?
Advice appreciated - confused!
