On the left hand side of the screen, the

SNo
., will be displayed and
the columns will have the headings:
NOM-Ø
, No.,
APRCH-X, APRCH-Y, TYPE, WID-R, C-SP,
FR
and
M
. Because we selected
Face Machining earlier, the rough and finish tools will be automatically
developed. On the next line, R 1 F-Mill will be displayed.

?<MENU>( )
•
Press the
AUTO SET menu key
This action will automatically set the approach
point a safe distance from the part geometry in the
X
axis. This value is
controlled by parameter setting and is typically 66% of the tool diameter.
Note: When AUTO SET is pressed, question
marks are temporarily entered until the part geometry is entered and the values
are changed relative to this geometry. The programmer can manually enter these
values, if known, or other values are preferred.

Select
X BI-DIR
from the Menu keys (F1
from the function keys).
X BI-DIR
stands for Bi-Directional cutting along the
X
axis; whereas,
X
or
Y UNIDIR
stands for cutting along
either axis in a single direction.
X
or
Y BI
or
UNI-DIR SHORT
means that the tool will
not position completely off the part but by only 33%.
Note: the
subheadings F1-F9 are not present on a MAZAK controller. These are function
keys on a standard keyboard and are used within the MazaCAM Editor only.
DEPTH OF CUT? ( )
•
Press the
AUTO SET Menu key
By selecting the AUTO SET function, the
controller calculates the difference between the full depth required and the
finish allowance determined earlier in the program, and inputs this amount. In
our case, it is .0402, because .0098 was the allowance and .050 is the stock
removal amount.
WIDTH OF CUT? ( )
•
Press the
AUTO SET Menu key
This value is based on 66% of the diameter of
the tool selected, which, in our case, is the three-inch face mill, so, by
pressing AUTO SET, the control will output approximately 2.7 for the width of
cut.
CUTTING SPEED, AUTO?<MENU>? ( )
•
Press the
AUTO SET Menu key
Pressing the AUTO SET Menu key uses the tool and
material data previously entered into the program to determine the cutting
speed (sf/min)
FEEDRATE, AUTO?<MENU>? ( )
•
Press the
AUTO SET Menu key
•
Pressing the AUTO SET
menu key uses the tool and material data previously entered into the program to
determine the cutting feed rate (in/min)
M CODE? ( )
Coolant flow is activated here. Two M-Codes may
be activated per tool.
