Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] refer to Figure 1 to Figure 5 , a kind of tool compensation method based on flat cutting machine, described method comprises the following steps:
[0021] (1) During the running process, the center point of the drawing pen is used as the running center point, and the offset L is introduced, that is, the offset L is added on the basis of the original coordinate point, so that during the cutting process, the cutting center point is The center point of the cutter, in order to facilitate the road planning during the cutting process, so that the cut graphics can coincide with the trajectory of the pen;
[0022] (2) The tool radius r is reintroduced to realize tool compensation;
[0023] (3) The cutter is a free-rotating cutter, and the cutter compensation method during the cutting process is as follows:
[0024] a. When lifting the knife, the linear tool compensa...

A cutter compensation method based on a plate cutting machine includes the following steps: (1) introducing offset L with a center point of a drawing pen as an operation center point in an operation process; (2) then introducing the cutter radius r used for achieving cutter compensation; (3) conducting cutter compensation with a cutter as a free rotating cutter. The cutter compensation mode in the cutting process is that a. linear cutter compensation is used in a cutter lifting process; b. combination of linear cutter compensation and arc cutter compensation is used in a cutter lowering process; c. combination of linear cutter compensation and arc cutter compensation is required when a cut material is thin and an included angle between a current line segment and a next line segment is smaller than a preset angle theta; d. combination of liner cutter compensation, arc cutter compensation, cutter lifting and cutter lowering are combined when the cut material is thick and the included angle between the current line segment and the next line segment is smaller than the preset angle theta. By means of the method, cutting accuracy and reliability can be effectively improved.
Description
technical field [0001] The invention belongs to the technical field of motion control, in particular to a tool compensation method based on a flat cutting machine. Background technique [0002] At present, the domestic flat cutting machine industry is developing rapidly, and various control systems are emerging. Flatbed cutters are ideal for tasks that require high precision and machining of medium-weight materials. At the same time, the flatbed cutting machine is also suitable for cardboard, mask film, foam board, oily board and other media. Some flatbed cutting machines have the ability to load a carving knife and a drawing pen at the same time, and the user does not need to manually replace the corresponding drawing pen and carving knife. And the choice of cutter is more and more diversified, there are free-rotating cutter, automatic rotating cutter, vibrating cutter and so on. Contents of the invention [0003] In order to solve the position deviation between the ac...
