Abstract: A machine tool includes: a display; a tool configured to machine a workpiece; a spindle configured to rotate the tool or the workpiece; a sensor configured to detect a vibration frequency of the spindle or the tool; and a processor configured to control the machine tool. The processor is configured to: detect a chatter vibration in the spindle or the tool based on the vibration frequency; based on a frequency of the chatter vibration, a rotation speed of the spindle, and the number of cutting edges of the tool, calculate an order corresponding to the number of vibrations of the tool during a period of time until a current rotation angle of a first cutting edge of the tool reaches a current rotation angle of a second cutting edge of the tool; and present order information on the display, the order information indicating a magnitude of the calculated order.

Abstract: The invention relates to a method of displaying a shape of a material and a shape of a product for a speedy machining simulation. In the machining simulation wherein the shape of the material, the shape of the product, and a shape of a tool are displayed as images on a display unit, and portions of the image of the material and the image of the product overlapping the image of the tool are successively eliminated, the shape of the product in accordance with a portion to be machined is displayed as a line image indicating only an outline of the product, on the other hand, the shape of the material is displayed as a plane image indicating an area in correspondence with a machining allowance, in case that the material includes the portion to be machined which is formed by adding the specified machining allowance to the outline of the product. Therefore, a data input in relation to the shape of the material can be simplified, whereby the speedy machining simulation is enabled.
