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 / min)
F = in mm / rotation or mm / min

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 / insertion directed by numerical (based on
number). Operating system parameters / CNC working system can be changed
through software programs (software load program) is appropriate.
The presence of CNC machines starting from the development system
Numerically Controlled (NC) in the late 1940s and early years
Found in 1950 by John T. Parsons, in cooperation
Company Servomechanism MIT. The presence of CNC machine
preceded by the discovery of NC machines which have the feature parameters
operating system can not be changed. CNC System on
initially use this type of hardware (hard ware), NC, and
403
computers used as a tool compensation calculations and
sometimes as a tool for editing.
At first CNC machines still use paper
hole as a medium for transferring G and M code to the system
control. After 1950, found a new method of transferring data
using RS232 cables, floppy disks, and last by
Computer Network Cables (Computer Network Cables) could even
controlled via the internet.
Lately, CNC machines have been developed
stunning, which changed the manufacturing industry during this
using human labor to full automation. Expanding
CNC machine, the workpiece can be made complicated sekalkipun
easily in large numbers.
We all know that the manufacture of components / spare
precision parts of a machine with manual machine tools
not easy, though done by a machine operator
advanced tooling solution even if it takes
long. If there is consumer demand to make components
High-tech in large quantities in short time,
with quality as good, it would be difficult to achieve when
using manual tools. Moreover, when the shape of objects
ordered more complicated, the harder it would be completed within
brief. Completion of the old product would be economically
increase production costs, product price will be
increasingly expensive, so more and more difficult to compete with products
Imported.

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 not

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 below:
