CNC machines are making parts around the world for almost every industry. They create things out of plastics, metals, aluminum, wood and many other hard materials. The word “CNC” stands for Computer Numerical Control, but today everyone calls it CNC. So, how do you define a CNC machine? All automated motion control machines have three primary components – a command function, a drive/motion system, and feedback system. CNC machining is the process of using a computer-driven machine tool to produce a part out of solid material in a different shape
Cnc tooling for cnc machine(130670119596)Kushal Shah
we have seen what the NC machine is and its various
parts, it is easier to understand what the CNC machine is. CNC is
the short form for Computer Numerical control. We have seen that
the NC machine works as per the program of instructions fed into
the controller unit of the machine. The CNC machine comprises of
the mini computer or the microcomputer that acts as the controller
unit of the machine. While in the NC machine the program is fed
into the punch cards, in CNC machines the program of instructions
is fed directly into the computer via a small board similar to the
traditional keyboard.
Computer Numerical Control (CNC) Machining is the process through which computers control machine-based processes in manufacturing. The kinds of machines controlled include lathes, mills, routers and grinders – all used for manufacturing of metal and plastic products.
Numerical control (NC) is the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium, as opposed to controlled manually.
Most NC today is computer numerical control (CNC), in which computers play an integral part of the control.
In modern CNC systems, end-to-end component design is highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

2. Chapter one - Computer Aided Manufacturing
• Introduction to CAM
• Introduction to Master CAM
• Creating 2D Drawings using MasterCAM software
• Creating 2D Tool paths
3. Introduction to CAM
1. What is computer aided manufacturing?
• Most machines need control systems to operate. There
are many kinds of control systems, for example, manual
control, automatic control, computer control or remote
control.
• For the convenience of mass production, machines need
to repeat precise, speedy and automatic actions
continuously.
• These machines may use mechanical, pneumatic and
electrical systems to control. However, some fixed
procedures, changing procedures or tools may need a lot
of time to restore the whole system (Fig. 1).
4. Introduction to CAM
1. What is computer aided manufacturing?
• As technology advances, electronic and computer
technologies have been applied to a lot of
production machines to reduce the production
time and increase both the quality and efficiency.
• So, modern factories usually use numerical control
machines, simply called NC machines. And an NC
machine that comes along with a computer is
called a computer control numerical machine,
simply CNC machine.
5. Introduction to CAM
1. What is computer aided manufacturing?
• A CNC machine uses digital information to
control the movements of tools and parts, for
example, the spinning speed, the cutting speed,
the moving direction of tools etc.
• So, we can change quickly the production
procedures simply by modifying the
information or program in the computer.
6. Introduction to CAM
1. What is computer aided manufacturing?
• The production method that requires a computer to
control the machines is called a computer aided
manufacturing, simply called CAM.
• CAM is closely related to the computer-aided design
(CAD) because the output information about the
products from the CAD can assist the composing of
production program. Tests and productions can start
immediately.
• This simplifies the procedures from the designing to
manufacturing of the product
7. Introduction to CAM
(a) The merits of computer numerical controlled (CNC)
There are many advantages of a CNC machine:
(i) The computer can design the best tool path, spinning
and cutting speeds of tools according to the information
of the product. This can help decrease the cost and
time.
(ii) CNC machines usually have automatic changing tools
function.
(iii) CNC machines can control precisely the tools
movement in any axis, so it can cut some complicated
work-piece efficiently.
8. Introduction to CAM
(iv) With the use of various input devices and the memories of
computer, a CNC machine can download and modify
program efficiently, so the production procedures can be
made quickly.
(v) In operating the CNC machine, manual adjustment is not
needed. Therefore, the CNC machine can run at a high
speed, and it requires less skillful workers to reduce the
labour cost.
(vi) CNC machine uses various designs to produce feedback, and
so it can keep its high reliability and quality, this can help
decrease the number of disqualified product and the cost of
inspection.
9. Introduction to CAM
(b) The restrictions of CNC machine
But, there are some restrictions of CNC machine:
(i) The cost of the machine is so high that some small
factories may not be able to afford.
(ii) Operators need to be trained to compose
computer control program.
(iii) The control system is complicated and
sophisticated, therefore the maintenance cost is
high.
10. Introduction to CAM
2. The industrial applications of CNC machine
(a) The design of CNC machine
• CNC machine needs new designs to suit the needs of
automation. Firstly, CNC machine needs a precise path
measuring system, so that the computer can detect the
position of tools and work-pieces automatically.
• There are many designs of path measuring system, for
example, using the photoelectric detecting device to
input the electronic signals into the computer directly.
11. Introduction to CAM
• Besides, to raise the preciseness, the tools of the CNC
machine should not be easy to bend and should have
good vibration absorbance.
• Also the ball bearing and axis should not have any offset,
and the driving system and axle should be able to keep
balance during the operation.
• Reduction of the frictional within the driving system can
reduce energy loss, increase efficiency, accuracy and the
maximum loading.
12. Introduction to CAM
• Besides, to raise the preciseness, the tools of the CNC
machine should not be easy to bend and should have
good vibration absorbance.
• Also the ball bearing and axis should not have any offset,
and the driving system and axle should be able to keep
balance during the operation.
• Reduction of the frictional within the driving system can
reduce energy loss, increase efficiency, accuracy and the
maximum loading.
13. Introduction to CAM
• On the other hand, the electromotor that drives the
rotation of the axle and tools should have precise
change and a large range of speed. The main axle also
needs a sensitivity device to ensure the angular
displacement when it is stationary, so that it is easier to
move or change the tools.
• Furthermore, the driving system of the punching press
needs to have a high motive force, good heat dissipation
capacity and high stability to provide a high press
capacity.
14. Introduction to CAM
2. The industrial applications of CNC machine
(b) Supporting machinery components
• CNC machine needs relatively more supporting machinery
components. For example, a tools clamp, an automatic tools
changing system, a tools holding device and a transfer
system, etc, are needed to make the changing of tools easier.
• Some machines use a turntable to store the tools allowing
the automatic system to change tools easier. Others use
robotic arm to change the tools or work-piece automatically.
15. Introduction to CAM
(c) Coordinate system
• CNC machine needs a coordinate system to control the tools.
For example, internationally used ISO R841 standardized
format is a common standard. Tools are needed to cut three
dimensional Work-pieces. That means that the tools will
move in a three-dimensional space. Therefore the coordinate
system should have three perpendicular axes.
• The axes used are called x-axis, y-axis and z-axis respectively.
Their respective position can be shown by making the thumb,
index finger and middle finger of the right hand perpendicular
to each other as shown Fig. 6a, called the right-hand rule.
17. Introduction to CAM
• The rotational axis can be set by the main axes, A, B
and C representing the rotational axes that rotate
about X, Y and Z axes respectively. Most of the
rotational axes take clockwise as positive value and
anti-clockwise as negative value, as shown in Fig. b.
• Furthermore, U, V and W are usually used to
represent the minor axes that are parallel to the
main axes X, Y and Z; P, Q and R are usually used to
represent axes that are far away but parallel to the
main axes X, Y and Z, for example, the axes on the
work-piece.
18. Introduction to CAM
(d) Introduction to various kinds of CNC machines
• There are various kinds of CNC machines, for examples, CNC
drilling machine, CNC lathe, CNC milling machine, etc.
(i) CNC drilling machine
• A CNC drilling machine uses holding device to hold the drill,
and then control the rotational speed of the drill, the depth
(Z-axis) of the drilling into the work-piece and its width. The
work-piece is usually clamped on the table that can move on
the surface (X and Y-axis). Because drills have different
length, therefore some CNC drilling machines use a program
to compensate for the depth of the drilling. Some CNC
machines have an automatic drill change system.
19. Introduction to CAM
(ii) CNC lathe
• Most CNC lathes need to control the X and Z-
axis, but some of them need to increase the
control of w-axis. Besides controlling the linear
path, CNC lathe can also control the rotational
speed of the rotational axis, cutting speed and
tools exchange, etc.
20. Introduction to CAM
(iii) CNC milling machine
• CNC milling machine can be divided into two kinds,
upright and horizontal, they usually have
continuous path controlling function, and they can
control motion that involved 3, 4, 5 or more axes.
• More than that, most CNC milling machines make
use of the computer’s calculation function to find
the linear or curve path between two points
automatically. That is why they can do cutting of
very complicated shapes.
21. Introduction to CAM
(iv) CNC machining center
• A CNC machining center is a common CNC machine
with many tools to do different tasks including surface
milling, drilling, boring, thread cutting and complicated
surface processing, etc.
• It can control 4 to 5 axes, and so it can cut 4 to 5
surfaces of a work-piece.
• The tools can be changed according to the program.
The number of tools involved are approximately 60 to
120, depending on the design of the tools depot
22. Introduction to CAM
(v) CNC turret press
• Punching is a process that uses a drift pin to
punch a hole, a pattern or small piece off a
metal sheet. CNC turret press usually have
many different shaped drift pin. It can move the
metal sheet quickly according to the CAD,
change a suitable drift pin, and punch the metal
sheet precisely and automatically.
23. Introduction to CAM
(vi) CNC press brake
• A CNC press brake not only can use computer to assist
in folding metal sheet, but also can coordinate with the
CNC turret press to fold metal sheet into joint vessel.
(vii) CNC spot welder
• Welding is a process that uses two electrodes to
generate electric current to weld metals. CNC spot
welder is commonly used in automobile industry where
several welders are used to form a welding production
line.
24. Introduction to CAM
(viii) CNC electro-discharge machine
• Electric discharge machining is a process that
uses metal threat and work-piece as electrodes,
and uses the electric spark generated between
them to cut hard work-pieces.
• CNC electro-discharge machine can use
computer program to cut complicated shapes
of work-pieces.
25. Introduction to CAM
(ix) CNC electron beam machine
• Electron beam machines (EBM) use high energy,
narrow, highly concentrated and high-speed electron to
weld, drill or do craft. When high speed electrons pass
through a vacuum and reach the metal surface, almost
all the kinetic energy of the electrons will be absorbed
by the work-piece and a large amount of heat will be
generated. Because electron beam can be used to do
various work, a computer numerical controller is often
used to operate the machine to simplify the process.
26. Introduction to CAM
(x) CNC laser cutting machine
• Laser cutting machines use high energy and
focused laser to cut metallic work-piece
precisely.
• CNC laser cutting can use computer program to
control the 2-dimensional movement of a work-
piece precisely, and so it can cut things into
complicated shapes.
27. Introduction to CAM
(xi) CNC coordinate measuring machine
• A coordinate measuring machine (CMM) is used to
measure the size of a work-piece or object precisely. It
can provide data of three dimensions, quality control or
modifying processing procedures of that object. It
usually uses many mutually perpendicular probes to run
through the surface of the measured objects to find the
coordinate of each point. CNC systems can control the
movements of the probes automatically, and collect,
save and process the data
28. Introduction to CAM
(xii) Other CNC machines
• There are many other functions of CNC machine,
for examples, CNC grinding machine, CNC pipe
deformer, CNC hydraulic cutting machine, etc. And
because computer technology is becoming more
and more powerful, it is for sure that more and
more CNC machines will be available, for example,
many factories start to use robotic arms to do many
processes.
29. Introduction to CAM
3 The operation of CNC machine
(a) Basic operation theory
• The Figure shows the simplified
operation procedures of a CNC
machine.
• Firstly, the engineering drawing

30. Introduction to CAM
• Then based on the information in the engineering drawing,
the computer numerical controlled machinery program (CNC
machinery program) will be composed.
• The CNC machinery program includes all the geometrical
and technical information. The geometrical information
decides the target position of the tools movement, cutting
direction and movement priority, etc.
• Technical information includes the choice of tools, the
rotational speed of the main axis, the rotating direction,
cutting speed, etc.
31. Introduction to Master CAM
• Master cam is a three-dimensional geometry
creation engine along with features to aid in tool
path generation and verification
• MasterCAM allows tool path planning and NC
code generation for a given part. This part can
either be drawn in MasterCAM or imported from
other CAD packages
