A mechanically guided reproducing machine that follows a full-scale model with a sensing point while a corresponding cutter removes marble.
Pantografo a palpatore is a mechanically controlled reproducing machine. According to Le voci del marmo, one point reads or follows the full-scale model while another works the marble, reproducing the sensed form.
Etymology
Italian: pantografo, “pantograph,” + palpatore, “feeler or sensing follower.”
Sculptor Notes
This machine sits historically between manual pointing and fully digital CNC reproduction. It mechanizes the relationship between model and copy while still depending on a physical model as the master.
