How does a CNC milling machine program a macro program for programming and machining a hemispherical surface?
How to program the macro program of the hemispherical surface part?
Today, take everyone to learn in the CNC milling machine, how to program the macro program to process the hemispherical surface, the task as shown
Let's think about how the surface should be processed. If you program the chamfer, then the principle of this part processing is actually the same.
Machining idea: any point on the contour of the tool to the surface corresponds to a coordinate (X, Z), and the coordinates (X, Z) of each point of the tool are (RCOS(θ), RSIN(θ)), where θ The range is [0,90]. Use the G02/G03 command to cut the plane corresponding to the X value for one week, and then move a Z to the next layer to repeat the circumferential cutting, so that the machining of the spherical surface can be completed.
The dimensions of the task map in this article are shown below.
Select a ball milling cutter with a diameter of 8mm. #2 is to control the depth of the lower knife. No tool compensation command is used. The programming procedure is as follows:
The final simulation effect is shown in the figure. There is a picture with the truth, I hope to help you!
