Abstract: There is provided a technique to estimate a cutting force by a new method other than use of a dynamometer. A machine tool capable of cutting a workpiece using a tool includes a first surface that receives a force due to the cutting of the workpiece, the first surface being located in the machine tool; and a second surface that receives a force due to the cutting of the workpiece, the second surface being located in the machine tool. The second surface is not parallel to the first surface, and the machine tool includes: a first strain sensor coupled to the first surface and the second surface; and an estimation unit that estimates a force applied to the tool, based on an output value of the first strain sensor during the cutting of the workpiece.

Abstract: There is provided an information processing apparatus for efficiently processing various products. The information processing apparatus includes a determiner that receives signals from sensors respectively provided in a plurality of machine tools, determines operation statuses of the plurality of machine tools, and derives a plurality of usable machine tools, a receiver that receives product specifying data for specifying a product to be manufactured, a decider that decides, based on the product specifying data, a necessary machine tool required to process the product, and a presenter that searches for the necessary machine tool from the plurality of usable machine tools, and presents information concerning a use machine tool as a search result.

Abstract: A machining state diagnosis apparatus (10) includes a machining state information estimation device (1), a learning information storage (11) storing information on relationship between estimated machining state information and actual machining state information, and a machining state diagnosis unit (12) 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 (1), and the relationship information stored in the learning information storage 11.

Abstract: There is provided an information processing apparatus for fully utilizing the functions of a machine tool by correctly converting CL data into an NC program. The information processing apparatus includes a CL data acquirer that can acquire CL data including standardization information based on a rule defined among a plurality of output devices, thereby acquiring CL data including the standardization information associated with at least one of unique control information of the numerical control apparatus, unique control information of the machine tool, and unique control information of a user of the machine tool, and an NC program generator that acquires an NC code corresponding to the standardization information included in the CL data, and generates an NC program including the NC code based on the NC code and the CL data.

Abstract: There is provided a vibration suppression device, a machine tool including the device and a vibration suppression method using the device. The vibration suppression device includes a flexible member having a first position F fixed to the structure to be a fixed end of a cantilever and a second position on a free end side; and a weight attached to the flexible member in the second position. The vibration suppression device has an adjustment mechanism for changing a distance between the first position and the second position. Accordingly, it can effectively suppress vibration of a structure, and that can effectively suppress the vibration by easy adjustment when the characteristic of a generated vibration is different.
