Abstract

The invention relates to a method and device for determining a cutter contact. The method comprises that a triangular plate model obtained by a discrete workpiece surface is determined; a bounding boxof a circular ring body of a cutter is established; and a candidate point of the cutter contact is determined. The candidate point is determined by determining a projection plane which comprises a projection direction, in which the cutter is projected to the workpiece surface, and the first side of the triangular plate model; determining a projection area of the cutter circular ring body in the first side according to an intersection point of the projection plane and the bounding box; searching the projection area for an optimal point which is a tangent point between the cutter circular ringbody and the first side; and taking the optimal point as the candidate point of the cutter contact in response to the optimal point found in the first side. The invention also describes a corresponding device, a computer system and a computer readable storage medium.

Description

technical field [0001] The present invention relates generally to the field of milling operations, and in particular to methods, devices and systems for determining tool contact. Background technique [0002] Computer Numerical Control (CNC) machining occupies a very important position in the manufacturing industry. For example, the commonly used vertical machining center (three-axis machining) has the problem that it can only perform simple plane machining, and can only process on one plane. With the continuous development of technology, five-axis machining technology has gradually been applied. Compared with three-axis machining, five-axis machining increases the freedom of two rotation axes, which can achieve better fit between the tool and the machined surface, reduce machining time, and improve surface machining accuracy. However, whether it is three-axis machining or five-axis machining, it is necessary to calculate the trajectory of the machining tool, especially fo...
