A machining state diagnosis apparatus () includes a machining state information estimation device (), a learning information storage () storing information on relationship between estimated machining state information and actual machining state information, and a machining state diagnosis unit () diagnosing a machining state in actual machining using control information, based on machining state information obtained during the actual machining, machining state information estimated based on corresponding control information by the machining state information estimation device (), and the relationship information stored in the learning information storage. The machining state information estimation device () includes an information storage () storing the control information and information on a workpiece and a tool, a machining state information estimator () estimating machining state information in relatively moving the workpiece and the tool, based on the information on the workpiece and the tool and the control information, and an image data generator () generating image data based on the estimated machining state information.
