1.1 The 3500i
Writing Programs
The 3500i allows many features to be used without having to write a
program. But for operations that repeat or complex machining it is best
to write a program. Before you start to write a program, determine the
work-holding device and the location of Part Zero (the point to which
all movement is referenced). Since absolute positions are defined
from Part Zero, try to select a location that directly corresponds to
dimensions provided on the part print, such as the lower left corner of
the work. Then, you can develop a program using a procedure similar
to the one that follows:
 The first block of a program is a safe starting position. This is where
the tool-change position (a location away from the work area where
the axes can return for safe tool changing) is input. The first block
includes the units of measurement (Inch/MM), mode of operation
(Absolute), move type (Rapid), and to cancel all auxiliary functions
(Tool Offsets, Spindle, and Coolant). This is the same as in g-code
(e.g. typical first blocks: G70, G90, G0, G28, Z0, & M5). Refer to
chapter 11 "G-Code on page 366”.
 Subsequent blocks in the program set Spindle information, call Tool
number, turn on Coolant, and make the initial move toward the
work.
 The remaining blocks in the program describe the required moves,
Canned Cycles, and Tool changes to complete the machining.
 The next to the last block in the program returns the axes to the Tool
change position, turning off any auxiliary functions (Tool Offsets,
Spindle, and Coolant). The last block , EndMain, (M2) ends the
program. This is the same as in g-code (e.g. typical last blocks: M5,
G0, T0, X0, Y0, Z0, M9; M2). Refer to chapter 11 "M-Code List on
page 370”.
 After writing a program, verify it. Run it in Draw Mode to troubleshoot
for errors. Verify that all programmed moves are safe, and accurate
to the part print dimensions.
 Load the stock material into the selected work-holding device.
 Set the Tool Offsets for each tool in the Tool Page.
 Before running the part in the Auto Mode, run it in Single-Step Mode
to verify that both the program and the setting of Tool Offsets have
been correctly completed. Single-Step Mode allows you to execute
the program block-by-block.
 After testing the program, make any necessary corrections.
 When the finished program is ready for production, back it up on a
USB memory device.
