Cutting apparatus

A cutting apparatus comprising:

• a platen configured to support a holding member for holding a workpiece;
• an attaching portion configured to hold a cutting blade;
• a first moving mechanism configured to move the holding member supported by the platen and the attaching portion relative to each other in a first direction and a second direction, the second direction intersecting the first direction;
• a second moving mechanism configured to move the attaching portion in a third direction and a fourth direction, the third direction intersecting the first and second directions and being a direction in which the second moving mechanism moves the attaching portion toward the platen, and the fourth direction intersecting the first and second directions and being a direction in which the second moving mechanism moves the attaching portion away from the platen;
• a pressure changer configured to change magnitude of pressure to be applied to the attaching portion in the third direction;
• a sensor configured to output a signal indicating a position of the attaching portion in a fifth direction, the fifth direction including the third direction and the fourth direction;
• and
• a controller configured to control the first moving mechanism and the second moving mechanism, the controller configured to execute:
• data obtainment including obtaining cutting data;
• target position specification including specifying a target position of the attaching portion in the fifth direction;
• movement control including controlling the second moving mechanism to move the attaching portion in the third direction;
• first determination while the controller executes the movement control to control the second moving mechanism, the first determination including determining whether a pressure corresponding value has reached a pressure threshold, the pressure corresponding value corresponding to the magnitude of the pressure applied to the attaching portion in the third direction by the pressure changer;
• second determination while the controller executes the movement control to control the second moving mechanism, the second determination including determining whether the attaching portion has reached the target position;
• first cutting control in a case where, before the controller determines, in the first determination, that the pressure corresponding value has reached the pressure threshold, the controller determines, in the second determination, that the attaching portion has reached the target position, the first cutting control including controlling the first moving mechanism based on the obtained cutting data and the second moving mechanism based on the pressure corresponding value achieved when the attaching portion is located at the target portion, thereby executing cutting processing, the cutting processing including cutting the workpiece using the cutting blade held by the attaching portion by moving the holding member and the attaching portion relative to each other in the first direction and the second direction;
• second cutting control in a case where, before the controller determines, in the second determination, that the attaching portion has reached the target position, the controller determines, in the first determination, that the pressure corresponding value has reached the pressure threshold, the second cutting control including controlling the first moving mechanism based on the obtained cutting data and the second moving mechanism based on the pressure corresponding value achieved when the attaching portion is located at a first particular position where the pressure corresponding value is equal to or lower than the pressure threshold value, thereby executing the cutting processing;
• third cutting control after executing the second cutting control, the third cutting control including executing the movement control to restart controlling the second moving mechanism;
• and
• thickness determination including determining a thickness of the workpiece based on the output of the sensor.
