Abstract: A processing apparatus and a processing method which perform processing more accurately with a simple structure are provided. The processing apparatus includes an irradiation head 16 and a control device. The irradiation head 16 includes a laser turning unit 35 and a condensing optical system 37. The laser turning unit 35 includes a first prism 51, a second prism 52, a first rotating mechanism 53, and a second rotating mechanism 54. The control device adjusts the differences between rotation speeds and phase angles of the first prism 51 and the second prism 52 based on a relation between at least a heat affected layer of a workpiece and a turning speed of laser.

Abstract: Provided are a machining device and a machining method in which machining of higher precision can be performed with a simple configuration. The machining device has an irradiation head (16) and a controller; and the irradiation head (16) can be divided into a collimate optical system, a laser revolving unit (35), and a light collection optical system (37). The laser revolving unit (35) has a first prism (51), a second prism (52), a first rotation mechanism (53), and a second rotation mechanism (54). The controller controls the rotational speeds and the difference in phase angles of the first prism (51) and the second prism (52), on the basis of at least the relationship between a heat affected layer of a member to be machined and the revolving speed of the laser.
