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

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

1. NC and CNC machines and Control Programming
Introduction to NC and CNC machines
CNC controls and RS274 programming
2. History of CNC
1949
US Air Force asks MIT to develop a "numerically controlled"
machine.
1952
Prototype NC machine demonstrated (punched tape input)
1980-
CNC machines (computer used to link directly to controller)
1990-
DNC: external computer “drip feeds” control programmer
to machine tool controller
3. Motivation and uses
To manufacture complex curved geometries in 2D or 3D
was extremely expensive by mechanical means (which
usually would require complex jigs to control the cutter
motions)
Machining components with repeatable accuracy
Unmanned machining operations
4. 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
7. Horizontal Milling machine architecture
Conventional milling machines
How does the table move along X- Y- and Z- axes ?
8. NC machines
Motion control is done by: servo-controlled motors
~
Servo Controller
Counter Comparator
Encoder A/C Motor
Input (converted from analog to digital value)
Table
Leadscrew
9. CNC terminology
BLU: basic length unit
smallest programmable move of each axis.
Controller: (Machine Control Unit, MCU)
Electronic and computerized interface between operator and m/c
Controller components:
1. Data Processing Unit (DPU)
2. Control-Loops Unit (CLU)
10. 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
11. 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
13. Open loop control of a Point-to-Point NC drilling machine
NOTE: this machine uses stepper motor control
14. Components of Servo-motor controlled CNC
Motor speed control
Two types of encoder configurations
Motor lead screw rotation table moves
position sensed by encoder
feedback
15. Motion Control and feedback
Encoder outputs: electrical pulses (e.g. 500 pulses per revolution)
Rotation of the motor linear motion of the table: by the leadscrew
The pitch of the leadscrew: horizontal distance between successive threads
One thread in a screw single start screw: Dist moved in 1 rev = pitch
Two threads in screw double start screw: Dist moved in 1 rev = 2* pitch
16. Example 1
A Stepping motor of 20 steps per revolution moves a machine table
through a leadscrew of 0.2 mm pitch.
(a) What is the BLU of the system ?
(b) If the motor receives 2000 pulses per minute, what is the linear
velocity in inch/min ?
17. Example 2
A DC servo-motor is coupled to a leadscrew (pitch 5mm) of a machine table.
A digital encoder, which emits 500 pulses per revolution, is mounted on the
leadscrew. If the motor rotates at 600 rpm, find
(a) The linear velocity of the table
(b) The BLU of the machine
(c) The frequency of pulses emitted by the encoder.
18. Manual NC programming
Part program: A computer program to specify
- Which tool should be loaded on the machine spindle;
- What are the cutting conditions (speed, feed, coolant ON/OFF etc)
- The start point and end point of a motion segment
- how to move the tool with respect to the machine.
Standard Part programming language: RS 274-D (Gerber, GN-code)
19. 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
