Addition controller, addition control method, and program

An addition control method for controlling an adding device configured to add molten metal layer by layer to form an object, control method comprising the steps of:

• acquiring shape data representing a shape of a three-dimensional object;
• dividing the shape data into a plurality of layers;
• for each layer among the plurality of layers
• determining a trajectory of the adding device that provides beads having an overlap ratio within a predetermined range,
• based on the shape data and the determined trajectory of the adding device, determine one or more segments of the determined trajectory having an overlap ratio that is outside of the predetermined range,
• adjusting an adding condition of the adding device based on the overlap ratio being outside the predetermined range, for each of the one or more segments, to form a layer with an upper surface having a layer flatness and an average height, and
• generating control information based on the trajectory of the adding device and the adjusted adding condition;
• and
• outputting the generated control information, wherein
• the layer flatness is controlled by the overlap ratio to achieve a predetermined flatness, and
• the average height is controlled by the adjusted adding condition of the adding device.

A non-transitory computer readable storage medium having stored thereon a program for controlling an adding device configured to add molten metal layer by layer to form an object, the program causing a processor to execute functions comprising:

• acquiring shape data representing a shape of a three-dimensional object;
• dividing the shape data into a plurality of layers;
• for each layer among the plurality of layers
• determining a trajectory of the adding device that provides beads having an overlap ratio within a predetermined range,
• based on the shape data and the determined trajectory of the adding device, determine one or more segments of the determined trajectory having an overlap ratio that is outside of the predetermined range,
• adjusting an adding condition of the adding device based on the overlap ratio being outside the predetermined range, for each of the one or more segments, to form a layer with an upper surface having a layer flatness and an average height, and
• generating control information based on the trajectory of the adding device and the adjusted adding condition;
• and
• outputting the generated control information, wherein
• the layer flatness is controlled by the overlap ratio to achieve a predetermined flatness, and
• the average height is controlled by the adjusted adding condition of the adding device.
