In CNC 4-axis machining, we can use the macro program to transform the coordinates and calculate the new coordinates of the point after the worktable rotates at any angle, so that the tool can be quickly positioned on this coordinate point on the workpiece.https://www.cncmachiningptj.com/laser-cutting
In CNC 4-axis machining, the coordinates of any point on the workpiece and the angle between the normal direction of the point and the Z axis of the machine are known. The macro program can quickly find the new coordinates of a certain point at any angle of the workpiece rotation, so that the tool can quickly Accurately locate the new point after the worktable rotates, so as to realize the coordinate tracking function of any point. Programming in the normal plane of the point can easily realize the rotation of the coordinate system. In the multi-faceted machining of complex workpieces, it can greatly reduce the alignment intensity of workers, and at the same time greatly simplify the programming, the efficiency is greatly improved, and it has strong practical significance.
CNC 4-axis machining
CNC 4-axis machining, in addition to X, Y, Z three axes, generally has a rotating table, vertical machining is A or B axis that rotates around X or Y. Horizontal machining is the B axis that rotates around the Y axis. Regardless of whether it is vertical or horizontal, when the workpiece is installed on the rotating table during processing, the operator needs to align the workpiece first, and then input the aligning value into the coordinate offset register of the numerical control system, thus confirming a Workpiece coordinate system. However, different parts have different shapes, processing positions and clamping postures, corresponding to different alignment datums, and the set coordinate systems are also different. However, for some workpieces, the die cutting china position corresponds to a certain angle relationship with the coordinate system determined by the alignment datum. The angle may be a variable, and the datum marked on the drawing is often the alignment datum. If the operator is processing this kind of workpiece without fixture positioning, different workpieces need to align the coordinate system, and careful and cumbersome calculations must be carried out each time the clamping is performed to find the offset of the coordinate of the processed point and the rotation center of the worktable. It is not only extremely inefficient and error-prone, but also takes up a lot of debugging time of the machine tool and increases the work intensity of the operator.
