13 CONCAVE Description A concave surface is shown in the following drawing.The curve is in theXZ plane (it can also beYZ plane.) We can caculate theZ coordinate with respecto X, then by using an appropreate ball mill machine the surface along the X axis. But the point by point calculation is very tedious and error proned. This CONCAVE feature can automatically preset the Z coodinate with respect to X, if the concave radius and the ball radius is known. CONCAVE RADIUS Rc Enter the CONCAVE mode THIS DRAWING IS NOT ON SCALE Press the fleXt key to scroll the MENU(section 6, page l0), until the COIVCAVE is displayed on the screen. Press the X, the Y or the Z Uey whichever happen to coincide with the CONCAVE CONCAVE mode. fr. iE 1'= \ELE{:E lnnnnn I tJ.U Lt t_t Lt The first screen selects the COIVCAVE in the XZ plane; the second screen selects the CONCAVE intheYZplane.

Creating a CONCAVE program There is a sample demo CONVEX program in the Mill Pro's memory, you can change it to create a new one, it may then be used as many times as required by running the I nn[ HuE [- frd l!_i ,= tnnnnn I L'.LI L' I-' L' Pressing the Z key to enter the desired CONCAVE RADTUS if different from the displayed value. Press the fleXt key to move to the next step. SET XY Z hfrL L [- frrJ lLl tr' fr. lPt l'= '=E l= H ,J Pressing the Z key to enter the desir ed BALL RADIUS if different from the displayed value. Press the ll€Xt key, the Mill Pro will display SEf X Y Z momentarily, then it will display the X, Y and Z dimension which is the starting position of the ball mill that shoud be set before machining.

This shows that the edge of the CONCAVE is higher than its ceter and if we start machining from (-3.0000, 0.0000, 0.0000,) we need set the coordinat equals to (-3.0000, 0.0000, 0.4695) SEfXYZscreen. Pressing the Staft key will make the Mill Pro to return to SEf X Y Z screen.
