Recently, the tooth profile of the internal involute finger milling cutter was calculated, but how do you verify the correctness of the results?
I thought of the previous verification method of the disc milling cutter, that is, to draw the tooth shape of the workpiece and the tool, assemble them together, and then move **, you can intuitively observe whether there is a phenomenon of interference, just do it
First establish the model of the internal gear, and the method of establishment can be seen in the previous article: "Recently, I have been tormented by spiral groove forming and milling", which will not be repeated here.
The tooth shape calculation of the tool refers to the calculation method of the tooth shape of the tool for the calculation of the tooth shape of the known helix workpiece in the "Gear Meshing Principle".
The tooth profiles on the left and right sides of the tool are symmetrical.
Assemble the established models together with the axis of the milling cutter perpendicular to the axis of the workpiece
The tooth top of the milling cutter is in contact with the tooth root of the workpiece:
The following is to increase the motion relationship on it, I here let the milling cutter be fixed, and the workpiece will move in a spiral. Let's take a look from a few different directions::
From the end face, it looks like this:
The workpiece is shown as transparent, take a look:
By observing the movement, there is no obvious interference between the milling cutter and the workpiece, and the preliminary judgment of the calculation result is correct, but it is not very certain, after all, this is not cutting**, there is no good persuasion, some friends suggested that I use Vericut for cutting**, this proposal is very good, I have time to verify it.
I amwoodykissme, regularly share the content of mechanical transmission and gear processing, and those who are interested in this aspect can follow me. I hope to be able to discuss it with you:
The design and processing methods of gears, and the design, manufacture and use of tools used in machining gears.
Gear cutter design calculation method, development of related applications, CAD secondary development, automatic drawing, etc.
In terms of tool application, the cutting parameters, coating and service life of the tool, the problems encountered in processing and solutions.
Share this today, and thank you for taking the time to read it!
