SINUMERIK 840D sl Commissioning Manual CNC: ShopTurn – 11/2006 Edition
$MM_CTM_CYC_ROUGH_MIN_REST_MA T1
Starting thickness, with reference to the final machining allowance, for machining residual
material (axis 1)
Min. input limit: 0
Protection level: 3/4
This MD is used to stipulate the limit value for machining residual material in the direction of
axis 1 (Z axis). This value also applies to stock removal, plunge–cutting, and groove tur-
ning.
Example:
If the MD is set to 50% and the final machining allowance is 0.5mm, any residual material
thinner than 0.25 mm is not machined in a separate machining step but is removed during
finishing.
MD 9555: $MM_CTM_CYC_ROUGH_MIN_RESET_MAT2
$MM_CTM_CYC_ROUGH_MIN_REST_MA T2
Starting thickness, with reference to the final machining allowance, for machining residual
material (axis 2)
Min. input limit: 0
Protection level: 3/4
This MD is used to stipulate the limit value for machining residual material in the direction of
axis 2 (X axis). This value also applies to stock removal, plunge–cutting, and groove tur-
ning.
Example:
If the MD is set to 50% and the final machining allowance is 0.5mm, any residual material
thinner than 0.25 mm is not machined in a separate machining step but is removed during
finishing.
MD 9554: $MM_CTM_CYC_ROUGH_MIN_RESET_MAT1
$MM_CTM_CYC_ROUGH_V AR_DEPTH
Percentage for variable cutting depth when turning a contour
Min. input limit: 0
Protection level: 3/4
Specify the percentage for changing the cutting depth when turning a contour. You can
select changing the cutting depth for stock removal and for removing residual material.
$MM_CTM_CYC_ROUGH_FEED_INT_TIME
Feed interruption time when turning a contour
Min. input limit: –
Protection level: 3/4
This MD is used to stipulate the feed interruption time for contour turning (removing stock,
plunge–cutting, plunge–turning). The MD is only evaluated if MD 9558
MM_CTM_CYC_ROUGH_INT_REL_DIST = 0.
> 0: Interruption time in seconds
< 0: Interruption time in revolutions
0: No interruption
