Example programs for CNC machine

Example for model processing with 3-axis CNC machine tool to get acquainted with programs we can do to order.

To review technical cards, start "SetupSheets" file that is in "For_shop_For3d.ru" folder.

The NC-code is in "ncprograms" folder and has *.TAP expansion, for example: "01_Koncevaya 10 mm.tap" is a file of 10 mm endmill trajectory.
The first part of a file name (before underlining) shows serial number of processing; the processing order can be also seen in the technical cards.

There are also files with *.INF expansion. They contain information about the tool and processing trajectory.
Files with NC-code or G-code contain data that operate the machine tool. They look as follows:

"%:0001 N 1 h0 N 2 (UAO,0) N 3 Z10 N 4 h02 N 5 T01

N 6 F 5000 it means that IDLE SPEED is 5000 mm\min (you can change this value depending on machine tool technical capabilities (if your machine tool’s speed is 15 mm\min put 15000 instead of 5000 and save the file)).
N 7 S 18000 M03 means that SPINDLE ROTATIONAL VELOCITY is 18000 rpm.

N 8 G0 Z9.95 N 9 G0 X837.26 Y-806.76 Z9.95 M08

N 10 G0 Z4.95
N 11 G1 Z-5. F1000 means that INSTRUMENT PENETRATION SPEED is 1000 mm\min (you can change this value depending on material, instrument and machine tool technical capabilities ("find and replace all" put 2500 instead of 1000 and save the file));
N 12 G1 Y-442.55 F4500 means that INSTRUMENT CUTTING SPEED is 4500 mm\min (you can change this value depending on material, instrument and machine tool technical capabilities ("find and replace all" put 1200 instead of 4500 and save the file));
N 13 G1 X832.31 Y-437.61 and etc. are COORDINATES, MACHINE TOOL FOLLOWS WHILE PROCESSING;
N 14 G1 Y-811.7 N 15 G1 X829.08 Y-814.93 N 16 G1 X827.31 N 17 G1 Y-434.37 N 18 G1 X822.32 N 19 G1 Y-814.93 etc. "
