Why CNC (Computer Numerical Control)?
It has been a privilege to be part of the Precision Machining
Technology Competition for the past 9 years. I am proud to have
the opportunity of working with the fine young people from all parts
of the United States. They deserve the best that the educational
system and VICA can provide to prepare them for a future in this
rapidly changing technological world and make their contribution

Memory Operation or Auto Mode
Programs are registered in memory in advance. When one on these programs is
selected and the cycle start switch on the machine operator’s panel is pressed,
automatic operation starts, and the cycle start LED goes on.
When the feed hold switch in the machine operator’s panel is pressed during automatic
operation, this operation is stopped temporarily. When the cycle start switch is pressed
again, automatic operation is restarted.
When...

AUTOMATIC OPERATION MODES
" MDI " OPERATION MODE
In the MDI mode, a program consisting of up to 10 lines can be created in the same
format as normal programs and executed from the MDI panel. MDI operation is used for
simple test operations.
In order to complete this operation, follow the next procedure:
1. Press the MDI mode selection switch.
2. Press the PROG function key on the MDI panel to select the program screen.
3. Prepare...
Learn to read program cnc lathe machine
If you look at the structure of a program cnc, What comes to your mind? Can you know how to read the program. Here I will explain my little knowledge about the structure of the program cnc.
examples:

Drill and Facing in the process of machining centers
From Blogger Pictures
Meet again with my post, this time I want to discuss about the drill and facing. I find obstacles to use of the tool joint and drill facing (can be seen in the image above). At the same drill a hole through it is with the process of facing. Obstacle I faced was the age of the tools that I use can not last long (often...
how to indicate command dimensions for moving the tool
How to indicate command dimensions for moving the tool
Command for moving the tool can be indicated by " Absolute Command or Incrimental Command "
Absolute Command
The tool moves to a point at "the distance from zero point af the coordinate system" that is to the position of the coordinate values
For milling:
Command specifying movement...
Speed and Speed Cut Feeds
Speed and Speed Cut Feeds
Cutting Speed (Vc)
Vc = (p x d x n) / 1000 (m / min)
d = Diameter Things Work
n = Number of rounds per minute (rpm)
p = Phi = 3.14
Vc Influenced by: a) Material, b) Types of cutting tools,
c) Speed feeds, d) Depth feeds
Speed feeds (F)
F (mm / min) = n (rev / min) x f (mm / rev)
Where: n = (Vc x 1000) / p x d (rev...
History of CNC machine
CNC stands for Computer Numerically Controlled,
machine tools are equipped with control systems
computer-based reading instruction code capable of N and G (Gkode)
which regulates the working system machine equipment, namely a
powered mechanical equipment used to make
component / workpiece. Machine tools are CNC machine
tool equipped with a variety of cutting tools that can be
make precise workpieces and can do
interpolation...
Insert Turning With Chip Breaker.Pdf
Our knowledge of the process feeds contributed in PDF files with the title of Turning Insert with chip breaker.
The process feeds in a machining process is very influential with the inserts that we use. In addition we need to know is Is it already there Insert the chip breaker or n...
CNC Mechine language and Basic ISO CNC code
Still in the discussion of CNC base. To post this time I can be from one of my friends blogs. I think it is very good because it is packed in PDF files with title MY CNC. Hopefully useful to all friends
we just see PDF file belo...
Function G Code on CNC Machining Center Machine
