7 Programming with Q Parameters<br />

7.8 Examples for Exercise<br />

Rectangular pocket with corner rounding and tangential approach<br />

7-14<br />

Pocket center coordinates<br />

X = 50 mm (Q1)<br />

Y = 50 mm (Q2)<br />

Pocket length X = 90 mm (Q3)<br />

Pocket width Y = 70 mm (Q4)<br />

Working depth Z = (–) 15 mm (–Q5)<br />

Corner radius R = 10 mm (Q6)<br />

Milling feed F = 200 mm/min (Q7)<br />

Note:<br />

At corners 21 and 31 the workpiece will be<br />

machined slightly differently than shown in<br />

the drawing!<br />
