The following movies are in German, they show how to work with nccad9.
The software itself is available in English, too, inside the software you can switch from German to English.
Even when you own a CAD - and CAM-program already, nccad is helpful.
You can read the words of the film in English, below the video.
You need Flash-Player and sound (for the German version).
Remarks: The nccad-window and the picture size was diminuated in order to reduce the size of the file.
Turn and mill
with a 4. axis (turning unit).
Turning contour with rotating workpiece, milled with X-Z-movement, then enter angle and mill surface or thread with X-Y-movement.
Turning and Milling together with the accessory Turning unit as 4th axis.
Select Turn and Mill, enter the workpiece dimensions, and get a screen with 3 axes: 1 turning contour, 2 XY-levels.
Example: I draw a polygon as turning contour: cone, line and out of the workpiece. This turning contour gets machining parameters (Technology): 2mm milling cutter, turning contour exterior, automatic path correction – taking into account the 2mm cutter, feed in X-direction, not very fast, and a related feed in Z. As partly infeed I enter 1mm, which makes an automatic finishing height of 0,1mm (can be changed). In the tab „Conditions" I choose a speed for roughing of 200 rpm, for finishing a speed of 400 rpm is proposed. After OK I can start Simulation and watch how the piece is turned.
Now I want to make surface machining in level XY, for example a rectangle from here to here, with its own technology: again 2mm milling cutter, type of machining „pocket hole", i.e. I empty a surface. In this case the feed in XY is e.g. 222, in XZ the value is half, the depth is e.g. 1mm in one step. As the piece has been turned down already, the starting height is now 6mm. OK. Simulation: You can watch the turning contour, then how the surface machining is done.
I want to repeat the surface maching in XY level with a start angle of 0° and a shift of angle of 90° 4 times. Simulation again: You can watch the surface machining repeated in 4 different angles.
Simulation in steps: Turning contour, finishing, 1st surface, 2nd surface, 3rd surface, 4th surface.
Turn and Mill is a very effective method to produce parts without having to re-clamp them.

nccad9 - Contour & Body STL
Milling 3-dimensional bodies with the function Quick & simple STL.
I get a choice of parts and select mechanical part STL. The part is displayed in the STL-viewer. I can watch it from each side. An assistant leads me:
First: 3 axes are available, „continue". The holes and the contour of the part must be milled accurately. It is not a so-called free-form piece but a mechanical part. The body has got the right size and the right position, therefore I can skip the functions "rotate" and "scale". "Continue".
The next step is to choose the material in which I want to mill the part, is it soft, medium or hard? Which milling cutter do I use? For roughing e.g. a 3mm milling cutter, for finishing the 1mm cutter. No micro-jet application, therefore „continue".
In this window you can define the type of milling around the piece. How is the piece clamped? Can I mill all around the piece, if yes, save and wait for the calculation of the milling paths. This may take some moments. In the simulation you can watch the holes and contour being milled. You can see first the big milling cutter, then the thinner one and the all-around milling in small steps. In this case the piece is supposed to be held from the bottom, i.e. it is either glued or screwed down.
You can go back to change the conditions of milling, e.g. to have supports generated automatically. Save again and „continue". The milling paths are calculated again, on the left and right you can see supports where the material is still connected to the crude piece.
This was to show how to get to a milled piece from a body designed in a 3D-CAD program.
