A contact determination unit determines whether the tool contacts the workpiece based on a measurement value related to main shaft flexure. A tool data correction unit corrects tool data based on the relative displacement when it is determined that the tool contacts the workpiece. A control unit generates a control command to control the jig or the tool based on the relative displacement, workpiece shape, and tool data.

WORK MACHINE AND METHOD FOR CONTROLLING WORK MACHINE
This work machine is provided with a vehicle body, traveling wheels, an actuator, a steering member, and a controller. In a case in which the steering member is positioned within the left steering range, the controller controls the actuator such that the steering angle of the traveling wheels is varied to the left at a speed depending on the control input imparted to the steering member. In a case in which the steering member is positioned within the neutral range and the steering angle is equal to or less than the threshold, the controller executes center return control for controlling the actuator such that the steering angle is returned to the neutral angle. In a case in which the steering member is positioned within the neutral range and the steering angle is greater than the threshold, the controller does not execute the center return control and maintains the steering angle.

A generation unit generates a virtual wall that is defined by a plane on a vehicle body coordinate system of which origin is a representative point of a swing body. A rotation conversion unit rotationally converts the virtual wall around the origin of the vehicle body coordinate system in association with a swing of the swing body. A position specifying unit specifies a position of an outer shell of a work machine in the vehicle body coordinate system. An intervention control unit controls the work machine such that the outer shell does not come into contact with the virtual wall.
An activation system for a work machine includes a communication unit, a presentation unit, and a determination unit. The work machine includes a power source and an additional function unit that realizes a predetermined additional function. The communication unit receives confirmation history information indicating an operator who has confirmed a precaution related to the predetermined additional function from a server device. The a presentation unit presents the precaution. The determination unit determines whether or not to omit presentation of the precaution based on the confirmation history information.

A stop system for an engine of a work machine includes an engine stop control unit and an engine stop control suspension unit. The engine stop control unit, in a case in which there is a stop instruction that instructs to stop the engine of the work machine, performs delayed stop control to delay the stop of the engine until a predetermined condition is established, and then stops the engine. The engine stop control suspension unit, in a case in which there is a cancellation instruction to cancel the stop instruction, suspends the delayed stop control when work equipment of the work machine is in a locked state, and continues to perform the delayed stop control when the work equipment is in an unlocked state.

This heat exchanger comprises: a plurality of tubes that are each formed in a flat tubular shape extending in a first direction, that have flat surfaces facing each other, and that each have formed therein an internal flow path through which an internal fluid flows along the first direction; and a fin that is disposed between the flat surfaces facing each other in the plurality of tubes and that is joined to the plurality of tubes such that an external fluid flowing outside the tubes flows, in a second direction that intersects the first direction, between the flat surfaces facing each other. In the fin, a plurality of undulations that are smoothly continuous are formed. Protrusions that protrude from the outer surface of the fin or holes that penetrate the fin are formed in the vicinity of peaks of the undulations. The fin has a guide structure that guides the external fluid toward the protrusions or the holes in the vicinity of the peaks of the undulations.
