3. Description on machine tools
A machine operator should create some basic selections concerning the sort of
machine tool to be utilized in any given method, as a wrong selection will mean
wasted material and in some cases, injury to the machine itself. This info might
sound to a small degree too basic to an experienced and competent
operator, except for those folks who do not know most, following may be
a fast overview of a number of the foremost common variations of machine
tools out there nowadays, and their uses
•Broaching tool
•Hobber
•Gear shaper
•Lathe
•Planer
•Hone
4. Broaching tool - a toothed
tool useful for removal of
fabric - will machine flat
surfaces making circular
and non-circular holes -
works particularly well with
forgings, medium-sized
castings, stampings and
screw machine elements.
Gear shaper - it cuts a person's
teeth of exterior and internal
gears, using different shapers.
5. Hobber - Useful for creating gears and sprockets - low value nonetheless
highly correct compared to alternative machine tools. You'll find different
types of hobbers like serration hobs, semi-topping gear hobs, earthworm
wheel hobs and straight facet spline hobs.
Lathe - Common little bit of pedaling for just about any machine look -
that's particularly produced for that cutting of round metal stock,
nonetheless it might create screw threads, tapering work, knurled surfaces
and contains the flexibility to drill holes.
Planer - An additional-large shaper that moves the whole table beneath
the cutter, enabling the setup of very correct flat surfaces because the
machine will need away an additional-large amount of metal with precision
throughout only one pass. It may cut slots like keyways.
Hone - An abrasive machining method where an abrasive stone is
scrubbed along a controlled route to raise the geometric surface in most
cases the very best texture - mainly useful for finishing cylinders for
engines, air bearing spindles and gears.
6. The Right Product for any Application
Only the right bearing support makes the sequence of movements
in machine
tools perfect. INA and FAG have been working for decades with
machine
and equipment manufacturers from a wide range of sectors.
Numerous new
product
developments are the result of these productive partnerships.
We produce customized application solutions that make machines
faster,
safer and more precise – in short – more economical.
On the following pages we will show you how we make this
possible.

7. Axial load on one side that is caused by
the stretching forces. In addition, DKLFA
bearings are extremely well suited for
vertical shafts in machine tools under
heavy loads. The outer ring leveled on
both
sides facilitates designs with extremely
low section heights. These are also
ready-to-mount.
The range is rounded off by FAG’s
single-row 7602, 7603 and BSB universal
bearings. They can be used in any
combination for specific operating
conditions.
You can find detailed product
information about ball screw supports
in INA Publication TPI 123 .
8. Reliability and Dynamics
Heavy-duty sprinter”: 40 % higher
running speed, robust
due to fewer components and
available with optional
roller chain – all in the same
mounting space!
Our compact model: four-row ball type
profiled rail units
combine high load carrying capacity and
rigidity with high
dynamics. An X-life product from INA
Linear Technology
10. Types of CNC machines
Based on Motion Type:
Point-to-Point or Continuous path
Based on Control Loops:
Open loop or Closed loop
Based on Power Supply:
Electric or Hydraulic or Pneumatic
Based on Positioning System
Incremental or Absolute
11. Advantages of CNC
- Easier to program;
- Easy storage of existing programs;
- Easy to change a program
- Avoids human errors
- NC machines are safer to operate
- Complex geometry is produced as cheaply as simple ones
- Usually generates closer tolerances than manual machines
12. Controller components
Data Processing Unit:
Input device [RS-232 port/ Tape Reader/ Punched
Tape Reader]
Data Reading Circuits and Parity Checking Circuits
Decoders to distribute data to the axes controllers
Control Loops Unit:
Interpolator to supply machine-motion commands between
data points
Position control loop hardware for each axis of motion
13. History of CNC
The RS274-D is a word address format
Each line of program == 1 block
Each block is composed of several instructions, or (words)
Sequence and format of words:
N3 G2 X+1.4 Y+1.4 Z+1.4 I1.4 J1.4 K1.4 F3.2 S4 T4 M2

15. Overview on machine shops
A machine search could be a workshop where materials like plastic, steel, and
glass are cut and formed with the assistance of machine tools. Machining is
that the method of removing material from raw stock and transforms it into a
usable half. Machine retailers use four separate and distinct processes to
switch a bit of metal into a machine. The modifying is finished by turning,
milling, drilling, and grinding.
