the first operation
The first stage, after surfacing a block of aluminum flat and parallel on both sides and adding some hold down slots, was to clamp it down on a scrap piece and machine the first side profile, using standard carbide endmills for roughing and ball endmills for finishing. The picture shows after this first operation is complete. We’ve added four bosses outside the actual part profile for hold down capscrews and dowels. They will be cut off in a later operation.
good project. all d best for best result. could you explain basic concept of design?
