Circular interpolation is a popular operation for CNC turning operators. The operation can be performed in any number of ways, with each method having its own benefits and drawbacks
The most common way to perform circular interpolation is to use an indexing method. This requires using a set of points around the circumference of the part that has been turned. The indexing system then moves along these points and keeps track of how far it has moved from its starting point
This method works well because it allows you to add new features or details without having to re-machining the entire part, which would require a lot of time and effort. However, this method does have some drawbacks. One problem with this method is that it requires a great deal of setup; you need to know where your part axis will be when you turn it, and then there are also some parameters that need to be set up before you start your program
Another way to perform circular interpolation is by using interpolation between two points on your part's surface rather than between two rotational coordinates on your part's surface itself as with an indexing method. This allows
