10. A method for controlling a server capable of communicating with a work machine having a work implement including a bucket, comprising:
receiving, at the transmitting, to a server from the work machine, identification information associated with the work machine; obtaining, by machine, wherein the server, based on the received transmitted identification information, obtains basic data used for calculating a position of teeth of the bucket, and the basic data is a dimension obtained based on manufacturing data of a component included in the work implement;
transmitting receiving, at the work machine from the server, the obtained basic data to the work machine data;
calculating positional information of the teeth of the bucket based on the received basic data; and
controlling operation of the work implement to prevent damage a design surface when the calculated positional information of the teeth are determined to reach the design surface, wherein when a controller determines that the teeth has reached the design surface, the controller automatically stops the work implement or moves the teeth of the bucket along the design surface via an assistive function.
