2. MACHINING MENU DESCRIPTIONS
– 165 –
YD : ESCAPE
Input the gap between the tool edge and the workpiece when the tool moves away from the work.
It is assumed to be 5 mm if there is no input.
3) Explanation of movements
a) When the operation (B) is a rough cutting operation.
1. Rapid traverse up to the starting point. (The approach clearance (YC) is considered)
2. Rapid traverse along the Z–axis up to the point equal to (point Z (Z) + Machining allowance (V))
– Pitch (J)
3. Cutting feed from the starting point on (U direction). (The escape clearance (YD) is considered)
4. Rise along the Z–axis in rapid traverse mode by escape clearance (K) in the Z direction + Pitch
(J)
5. Rapid traverse along the X–Y axes to the point determined by taking into consideration at the
starting point the cutting width (E).
6. Descent along the Z–axis in rapid traverse mode by an amount equal to the the escape clearance
(K) in the Z direction + Pitch (J).
7. 3. – 6. is repeated.
8. Rapid traverse along the Z axis to the point corresponding to the work surface + amount in the
Z direction (K).
9. Repeat steps 1. to 8. advancing in the –Z direction, pitch by pitch, up to the point equal to point
Z (Z) + Finishing allowance (Y).
10. Rise along the Z axis up to the common safety point Z.
NOTE Refer to 2.3.1 3) for the processing of the remainder.
b) When the machining operation (B) is a finish cutting operation.
1. Rapid traverse up to the starting point. (The approach clearance (YC) is considered)
2. Rapid traverse along the Z axis up to point Z (Z).
3. Cutting feed to the other side of the starting point (U direction). (The clearance (YD) is considered)
4. Rise along the Z–axis in rapid traverse mode by an amount equal to the the (K) in the Z direction
+ Finishing allowance (Y)
5. Rapid traverse along the X–Y axes back to the point determined by considering the cutting width
(E) at the start point.
6. Rapid traverse along the Z axis up to the point Z (Z).
7. 3. – 6. is repeated.
8. Rise along the Z axis up to the common safety point Z.
