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.
