First, draw the part (CAD). Then, set the cut and check it in 3D (CAM).
Both were recorded on a phone, so you can follow along at the machine.
It starts where most jobs really start: with nothing but a paper drawing. Instead of drawing line by line, you type the numbers written on the paper. If you do have a DXF, you just load it.
One sheet per operation: pick the insert you actually have, set the depth of cut, and recalculate. Then play every operation through in 3D and watch bar stock turn into the part — before the machine ever runs.
Just the parts that tend to trip people up the first time.
Instead of drawing lines, you place points in order. Type only a diameter and it stands up a face; type only a Z and it runs along the diameter. The value you skip carries over from the last point, and the closing segment back to the start is added automatically — no overall length to work out.
Assigning each drawn line to the operation that will cut it. Outside to OD, bore to ID, groove to GROOVE. That colouring becomes the list of operations.
The bar you start from. Add clearance and it shows the actual diameter the cut will start from.
The correction that cancels out the under- and over-cut a round insert tip leaves on tapers and radii. In LATHE-NC you pick the insert; the maths is applied for you.
Runs every registered operation from the top in 3D. Each one inherits the shape the previous one left, so collisions and leftover material caused by the operation order show up exactly as they would on the machine.
Every operation joined into a single G-code file. Copy it and take it to the machine.
