[CAD/CAM/CNC] Lesson 17: Siemens Sinumerik Milling Programming Example ------------------- A very simple cnc milling program example which will show cnc machinists the use of Siemens Sinumerik milling programming concepts. This program is written for 4-axis cnc mill, where C is used for rotary table. But a simple cnc mill can also run this program just remove program block N15 Contents Sinumerik Milling Program Finished Part Explanation of G-Code Sinumerik Milling Program Sinumerik Mill Programming Example N5 G00 G54 G64 G90 G17 X-20 Y-20 Z50 N10 S450 M03 F250 D01 (12.5 MM DIA) N15 C0 N20 Z5 N25 G01 Z0 N30 Z-5 N35 G42 X0 Y0 N40 X30 N45 Y30 N50 X0 N55 Y0 N60 G40 X-20 Y-20 N65 G00 Z50 N70 Y100 N75 M30 Finished Part After the machining is complete, this finished part will look like this Finished Part Explanation of G-Code G00 – Rapid traverse.

[CAD/CAM/CNC] Lesson 14: Mill Programming Exercise using G91 Incremental Programming ------------------------ This CNC mill programming exercise will give you more idea to understand drawing and how to find exact coordinate of each drawing point. Completely based on G91 Incremental Dimensioning System, so cnc programmers/machinists can learn and understand how G91 Incremental Programming works. This program is written for 4-axis CNC mill, where C-axis is used for rotary table. 3-axis CNC mill can also run this program, so for this just remove program block no. N15.
