In accordance with one embodiment of the present invention, there is provided a device for measuring length of feedstock being fed to a tool operated directly by a user. The device includes a body, configured to be removably attached to the tool. The device also includes a display, mounted in the body, and visually accessible to the user. The device also includes a measurement wheel mechanically mounted to the body and configured to be mechanically biased to the feedstock under a condition wherein the body is attached to the tool. The device also includes an encoder coupled to the measurement wheel and configured to generate a signal indicative of angular position of the wheel. The device further includes a processor, disposed in the body, coupled to the encoder and the display and configured to cause the display to show a measure indicative of a length of the feedstock that has been fed to the tool.

A controller of a cutting apparatus obtains cutting data and specifies a pressure value corresponding to pressure to be applied to an attaching portion by a pressure changer during cutting processing for cutting a workpiece using a cutting blade based on the cutting data and a target range defining target positions of the attaching portion in a fifth direction. While causing the pressure changer to apply, to the attaching portion, the pressure corresponding to the specified pressure value, the controller executes the cutting processing by controlling a first moving mechanism and obtains the position of the attaching portion in the fifth direction. If the obtained position of the attaching portion is out of the target range, the controller changes the pressure value to another value and executes the cutting processing while causing the pressure changer to apply, to the attaching portion, the pressure corresponding to the other value.
