Abstract

An apparatus and a method for machining valve seats in a cylinder head of an internal combustion (IC) engine are disclosed. The apparatus includes a spindle and a tool for machining said valve seats utilizing an automated cycle. The apparatus switches operation from the automated cycle to a manual mode upon detecting an irregularity in machining of the valve seat, for example. The apparatus allows an operator to adjust the spindle, the tool or the parameters in the manual mode. The apparatus switches the operation from the manual mode to the automated cycle based on the spindle, the tool or the parameters adjusted for machining the valve seats. The apparatus includes a rotary encoder configured to capture accurate position of the spindle, the tool, and rotation direction of the tool and provide feedback to the controller for optimizing the machining of the valve seats.
