One or more example embodiments of the present invention relates to a fin for collimating therapeutic radiation. The fin comprises a collimation area made of a first material and a holding area made of a second material. Herein, the collimation area and the holding area are pressed together. Herein, the first material is formed to collimate therapeutic radiation. Herein, the holding area can be coupled to an adjustment device for adjusting the fin.

A thermal displacement compensator measures a temperature of an environment in which a machine is installed and a temperature of each part of the machine, and calculates a temperature difference between at least two temperatures among measured temperatures. Furthermore, the thermal displacement amount of the machine is acquired. Then, based on teacher data using the measured temperatures and the calculated temperature difference as input data and using the acquired thermal displacement amount as output data, a thermal displacement compensation model that estimates the output data from the input data is created by machine learning.

A follow-up swing head type large taper wire cutting device is disclosed. In the large taper wire cutting device, swing heads on upper and lower mechanical arms are adjusted in a follow-up way by swing head rotating mechanisms in coordination with a cutting taper, universal wire guide wheels are used to cooperate with the corresponding upper and lower swing heads, and tensioning mechanisms between the universal wire guide wheels and directional wire guide wheels are used for transition to ensure the smooth transition of an electrode wire, so that the electrode wire is effectively prevented from sliding off during large taper cutting, and the control of the follow-up deflection position of the electrode wire is also very accurate.

A wire electrical cutting machine for machining a circular part by a wire electrode.

There is provided a wire electrical discharge machine that includes a temperature detection unit, an actual position correction amount calculation unit, a correction amount calculation unit, a correction amount adjustment unit, a position correction amount adjustment unit, and a corrective movement amount calculation unit. The actual position correction amount calculation unit calculates an actual position correction amount for an upper/lower guide section in accordance with reference position coordinates at a reference temperature and with actual position coordinates at a temperature different from the reference temperature. The correction amount calculation unit uses a prepared correction amount arithmetic expression. The correction amount adjustment unit calculates a correction amount adjustment value from the actual position correction amount and the position correction amount.
