[0003] It can be seen from the above that CAD and CAM software only use machining program codes to roughly simulate machining and cutting results. In other words, the existing technology is to input the machining program codes into the machine tool and perform volume elimination according to the machining path of the machining program codes. As the cutting simulation result, it can only simulate whether the tool interferes with the machine tool, or simulate the height of the residual material on the cutting die surface, and does not include the simulation results of dynamic errors caused by control, interpolation, and machine tool structure.
Therefore, the cutting simulation method using CAD and CAM software in the prior art cannot reflect the real situation that dynamic errors cause defects on the die surface, and the calculation of volume elimination will make the calculation time too long

A method for simulating cutting using dynamic position error, suitable for connecting to a controller of a machine tool, including the following steps: generating a cutting die surface using a machining program code; calculating the normal vector of each grid point in the cutting die surface; according to various position commands and corresponding position feedback, obtaining the three-axis dynamic error on the cutting die surface; calculating the component of the normal vector of the three-axis dynamic error on the cutting die surface to obtain the normal vector error value of each grid point; and displaying the overcut information of the normal vector error value at the corresponding grid point on the cutting die surface.
Description
technical field [0001] The invention relates to a simulated cutting method, in particular to a simulated cutting method utilizing dynamic position error. Background technique [0002] When simulating machining and cutting, in order to predict the impact of errors on the die surface, the existing technology usually uses CAD and CAM software, such as NX, CATIA, VERICUT, etc. Generally, in the method of simulating machining and cutting using CAD and CAM software, the machining program code input to the machine tool is used to let the tool follow the machining path of the machining program code to eliminate the intersection volume of the workpiece and the tool to remove material to achieve simulation. The purpose of machining and cutting. [0003] It can be seen from the above that CAD and CAM software only use machining program codes to roughly simulate machining and cutting results. In other words, the existing technology is to input the machining program codes into the machi...
