Sewing data editing device, non-transitory computer-readable medium, and sewing machine

A non-transitory computer-readable medium storing computer-readable instructions that are executed by a processor of a sewing data editing device, the computer-readable instructions performing processes comprising:

• acquisition processing of acquiring coordinate data representing a position of each of a plurality of points along a predetermined pattern;
• corner portion detection processing of detecting, based on the coordinate data of each of the plurality of points, a corner portion, in the predetermined pattern, having an angle smaller than a predetermined angle;
• and
• editing processing of editing sewing data, based on the coordinate data of each of the plurality of points and on a detection result of the corner portion detection processing, using editing conditions that are mutually different for a plurality of first needle drop points corresponding to the corner portion and for a plurality of second needle drop points corresponding to a non-corner portion not detected as the corner portion, in the predetermined pattern, the sewing data being data for performing couching, using a sewing machine, to directly sew a cord member onto a sewing object, by forming a plurality of sewing stitches penetrating the cord member and the sewing object along the predetermined pattern.

A sewing machine comprising:

• a movement mechanism including a motor configured to move a sewing object in a first direction and a second direction orthogonal to the first direction;
• a needle bar mechanism including a needle bar to a lower end of which a sewing needle is detachably mounted, the needle bar mechanism being configured to drive the needle bar to reciprocate in an up-down direction;
• a processor;
• and
• a memory configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes comprising:
• acquisition processing of acquiring coordinate data representing positions of each of a plurality of points along a predetermined pattern;
• corner portion detection processing of detecting, based on the coordinate data of each of the plurality of points, a corner portion, in the predetermined pattern, having an angle smaller than a predetermined angle;
• editing processing of editing sewing data, based on the coordinate data of each of the plurality of points and on a detection result of the corner portion detection processing, using editing conditions that are mutually different for a plurality of first needle drop points corresponding to the corner portion and for a plurality of second needle drop points corresponding to a non-corner portion not detected as the corner portion, in the predetermined pattern, the sewing data being data for performing couching, using the sewing machine, to directly sew a cord member onto the sewing object, by forming a plurality of sewing stitches penetrating the cord member and the sewing object along the predetermined pattern;
• and
• sewing control processing of driving the movement mechanism and the needle bar mechanism in accordance with the sewing data edited at the editing processing, and performing the couching.
