There is a thread that is tangent to the top and bottom of the arc on the outer circle of military parts in a factory (drawing dimensions are confidential)
They use custom-made forming tools like the photo below
In this way, the tool cost is high, vibration is prone to occur during the cutting process, and it is difficult to meet the surface roughness requirements of the thread;
How to do?
Standard external turning tool can be used for processing:
such:
1. Low tool cost
2. No vibration
3. It is easy to ensure the surface quality of the thread
How to program it?
Just three steps:
1. First compile a program for fine turning this kind of thread;
2. On the basis of the fine turning program, add a variable representing the amount of X to remain, so that it can be used for rough turning;
3. Combine the coarse and fine turning programs to make it a general-purpose macro program for continuous coarse and fine turning of this kind of thread;
In this program, we parameterize the tool fillet, workpiece size, etc., like this:
No matter the size of a certain thread of this type to be turned...
No matter how big the radius of the turning tool is...
Regardless of the number of layers of the car, what cutting parameters are used for each layer...
You can use this program to continuously make rough and precise turning!
