  • Publication number: 20150231789
    Abstract: A cutting apparatus moves a cutting blade and an object to be cut relative to each other based on cutting data, thereby cutting a pattern out of the object. The apparatus includes an extraction unit extracting from the cutting data positions of cutting start and end points of cutting line and a setting unit changing the positions of the points to a position on the cutting line other than a specified position on the cutting line when the extracted positions are on an apex of neighboring line segments of the cutting line, in a case where a closed pattern is cut out. The cutting line includes continuing line segments, and the setting unit sets the cutting start and end points at the line segment within a successive obtuse angle region where an obtuse angle that is made between neighboring line segments and is not less than a threshold is successive.

  • Patent number: 9067330
    Abstract: A cutting apparatus includes an angle change unit configured to change an angle made by a cutting blade and an object to be cut. The angle change unit is configured to change the angle between a first angle during a non-cutting time and a second angle at which the blade is tilted during a cutting time so that the second angle is rendered smaller than the first angle. The first abutment limits a swinging movement of the blade while the first angle is made by the blade and the object. The second abutment limits the swinging movement of the blade while the second angle is made by the blade and the object. The angle between the blade and the object is changed from the first angle to the second angle by resistance to which the blade is subjected from the object with the relative movement of the blade.
