Technical Field
The utility model relates to the technical field of five-axis machining measurement, in particular to a tool jig for measuring five-axis rotation precision.
Background
Five-axis machining is a machining mode of a numerical control machine tool, and a right-hand rectangular coordinate system is adopted when describing the motion of the numerical control machine tool; wherein the coordinate axes parallel to the principal axis are defined as the z-axis, and the rotational coordinates about the x, y, and z-axes are A, B, C, respectively. The movement of each coordinate axis may be accomplished by the movement of the table or the tool, but the direction is defined by the direction of movement of the tool relative to the workpiece. Typically five-axis linkage refers to linear interpolation motion of any 5 coordinates in x, y, z, A, B, C. In other words, five axes refer to three axes of movement x, y, z plus any two axes of rotation. Five-axis machining refers to machining of parts with relatively complex geometries, as opposed to the common three-axis (x, y, z three degrees of freedom) machining, requiring that the machining tool be capable of positioning and coupling in five degrees of freedom. The machine tools used for five-axis machining are commonly referred to as five-axis machines or five-axis machining centers. Five-axis machining is commonly used in the aerospace field to machine body parts, turbine parts, impellers and the like with free-form surfaces. The five-axis machine tool can process different sides of the workpiece without changing the position of the workpiece on the machine tool, and the processing efficiency of the prismatic part can be greatly improved.
