Classification: CPC B | IPC B

Claim 1:
2. The cutting device according to claim 1, wherein
the detecting the pressure correspondence value and the movement amount includes detecting
a first pressure correspondence value that is the pressure correspondence value corresponding to a first pressure, and a first movement amount that is the movement amount of the mounting portion when the first pressure is applied to the mounting portion,
a second pressure correspondence value that is the pressure correspondence value corresponding to a second pressure, and a second movement amount that is the movement amount of the mounting portion when the second pressure is applied to the mounting portion, and
a third pressure correspondence value that is the pressure correspondence value corresponding to a third pressure, and a third movement amount that is the movement amount of the mounting portion when the third pressure is applied to the mounting portion, the second pressure being larger than the first pressure, and the third pressure being larger than the second pressure, and

the deciding the cutting pressure correspondence value includes
calculating, on a basis of a change amount of the pressure correspondence value from the first pressure correspondence value to the second pressure correspondence value, and a change amount from the first movement amount to the second movement amount, a predicted value of the movement amount of the mounting portion when the third pressure is applied, and
deciding the cutting pressure correspondence value on a basis of the third pressure correspondence value when a difference between the third movement amount and the predicted value is equal to or greater than a predetermined difference threshold value.
