7 Programming with Q Parameters<br />
7.8 Examples for Exercise<br />
Machining a hemisphere with an end mill<br />
<strong>TNC</strong> <strong>360</strong><br />
Notes on the program:<br />
• The tool moves upwards in the ZX plane.<br />
• You can enter an oversize in block N120<br />
(Q12) if you want to machine the contour<br />
in several steps.<br />
• The tool radius is automatically compensated<br />
with parameter Q108.<br />
The program works with the following values:<br />
• Solid angle: Start angle Q1<br />
End angle Q2<br />
Increment Q3<br />
• Sphere radius Q4<br />
• Setup clearance Q5<br />
• Plane angle: Start angle Q6<br />
End angle Q7<br />
Increment Q8<br />
• Center of sphere: X coordinate Q9<br />
Y coordinate Q10<br />
• Milling feed rate Q11<br />
• Oversize Q12<br />
The parameters additionally defined in the<br />
program have the following meanings:<br />
• Q15: Setup clearance above the sphere<br />
• Q21: Solid angle during machining<br />
• Q24: Distance from center of sphere<br />
to center of tool<br />
• Q26: Plane angle during machining<br />
• Q108: <strong>TNC</strong> parameter with tool radius<br />
