WORK NO. (NAME SEARCH <?INP> ( )
•
Key in the
desired work number (program number) i.e., 2525 and press Input. It is a good
idea to check the Program File prior to this step in order to identify program
numbers that have been used. At this point, there is a Menu option to program
in either EIA/ISO (G-Code or
MAZATROL). Note:
On some older
model controls (M2 – M32 – M+) the EIA/ISO selection was an option and may not
be available.
•
Select
MAZATROL from the Menu keys You are now ready to create the Common Data Unit
which will be listed on the screen as Unit #0. The first prompting question
encountered is:
MATERIAL <MENU>? ( )
From the Menu options, you should select the
material that most closely matches the material you are using. This selection,
along with the tool file information, affects the automatic calculation of
feeds and speeds later in the programming process.
•
Select
AL
from the Menu keys and
Press Input
The material choices are given above the menu
keys on the control and abbreviations for materials are; :
CST IRN
= Cast Iron;
DUCT IRN
= Ductile Iron;
CBN STEEL
= Carbon Steel;
ALY STEEL
= Alloy Steel;
STNLESS
= Stainless Steel;
AL
= Aluminum;
COPPER
= Copper. The last Menu
key on the right has arrows pointing to the right
(→ → → →)
for a second page of
additional material selections. These can be used for user defined materials.
Note: All Cutting Condition Parameters
are based from Carbon Steel (e.g. Plain Carbon Steel 1018). All other materials
are a percentage factor of this. You may develop new materials specific to your
application with this criteria in mind. See the section in your Mazak User
Manual provided with the machine for details on assigning Cutting Condition
Parameters.
INITIAL POINT- Z (CLEARANCE)?
( )
For specific details, see the preceding text in
this section for a description of Initial Z Clearance question to establish the
Z Plane.
•
Key in 1.0
and press Input
ATC MODE ZERO RETURN <Z.X+Y:0,
X+Y+Z:1>?
(
) This sets the path the spindle is to take for the Automatic Tool Change Mode.
See existing text for a more detailed description of ATC MODE.
•
Key in 0 to
select the Z first then XY movement and Press Input
MULTI MODE
<Menu>?
See the existing text in this section for
details regarding whether there are multiple parts on the table, or not.
•
Select
MULTI OFF from the Menu keys
MACHINING UNIT <MENU>?
( )
The following choices are available to choose
from: POINT; LINE; FACE; MANU
Part
AL
PROGRAM; OTHER; WPC; OFFSET; END and, SHAPE
CHECK. (See Figure 8).
•
Choose WPC
from the Menu select keys
This is UNo.1 WPC = Workpiece Coordinate. Use
this unit to identify the location for the part zero of the geometry from
machine home. These values are usually measured using an edge finding device or
probe system and input within the program or the offset registers. You may also
set this item to use G54-G59 and additional offsets of A – K. Consult the
Operation Manual of your machine for specific instructions on setting these
values. A number can be assigned, in order to include multiple WPC’s within the
same program.
•
Press Input
or use the right pointing cursor key to accept a value of 0 for our WPC number
•
Press Input
again to pass over the Additional Offsets
At this point, you will be prompted as follows:
WORKPIECE COORDINATE, WPC - X? ( )
WORKPIECE COORDINATE, WPC - Y? ( )
WORKPIECE COORDINATE, WPC -
è?
( )
WORKPIECE COORDINATE, WPC - Z? ( )
WORKPIECE COORDINATE, WPC - 4? ( )
•
Input 0 in
each case for now
Setup Notes: The exact coordinate values
for each of these offsets will be measured during the setup process and entered
via WPC-MEASURE, WPC SEARCH. Position an edge finding device in order to find
the workpiece edge along the X axis. Press the TEACH Menu key and key in a
value (0) that represents the location of the spindle, in relation to the
Workpicece Zero, and Press Input. Don’t forget to compensate for the radius of
the edge finder. Repeat these steps for the Y axis. Input 0 for the workpiece
rotation angel of Theta. All cutting tools used in the program should be
installed in the magazine and measured to the tool sensor prior to workpiece
coordinate setting. For the WPC – Z, position any tool that is used in the
program and touch off the top most surface of the part. Remember, sometimes
this top-most surface is above the finished surface zero. This is the case in
our example, so once the tool is touched-off along the Z axis, Press TEACH, key
in -.05 and Press Input. Input 0 for the 4th axis workpiece coordinate.
When all these data are
entered, a new unit (UNo.2) is started.
MACHINING UNIT <MENU>? ( )
Often, it is necessary to machine the work
surface to establish a Z -0 work face. It is commonly at the beginning of the
program for this reason. The following choices are available to choose from for
Face Machining:
FACE
MIL; TOP EMIL; PCKT MT; PCKT VLY
. (See Figure 8).
•
Select
FACE MIL
from the Menu keys
Figure 19 Face Machining
Menu Keys
Once the Face Machining menu key is pressed,
there are columns with the following headings displayed on the screen: DEPTH,
SRV-Z, BTM and
FIN-Z.
DIST:
WPC Z0 TO FIN SURFACE? ( )
•
Input 0
here because this represents our finished surface for Z
Z AXIS STOCK REMOVAL? ( )
•
Input .05
here because there is that much excess material to remove
BOTTOM ROUGHNESS <MENU>? ( )
•
Choose from
6 from the Menu keys
This will automatically set the Z depth of cut
for the roughing (.0402) and finishing (.0098) passes. A number system of 1-9
is used here that relates to surface finish. Higher number the more fine the
finish. This number affects the finish depth of cut.
•
Press Input
Figure 20 Bottom and
Wall Roughness Menu Keys
The following Figure identifies the approximate
surface Micro Finish that is created when each of the numbers are selected. For
example, selection of Menu key 6 will produce a 32 Micro Finish.
