Abstract
A machining apparatus in which the machining efficiency can be improved even if characters are machined in a printed circuit board. A coordinate transformation unit is provided for transforming central coordinates of each dot d of each character of a character string into coordinates in a machining coordinate system with which the holes will be machined. Prior to machining, based on a character string and position information of the character string described in a machining program, central coordinates of each dot of each character of the character string are transformed into coordinates in the machining coordinate system with which the holes will be machined. Each dot d is regarded as a hole and machined. The number of times of movement of a table can be thus minimized so that the machining efficiency can be improved.
