Integrated Product Development (IPD) (Better)
Integrated Product Development is a philosophy that systematically employs a teaming of functional disciplines to integrate and concurrently apply all necessary processes to produce an effective and efficient product that satisfies customer's needs. Product, in this sense, is not only what is delivered to customer (e.g., hardware, software, services, and documents), but also processes (e.g., design, manufacturing, test, and logistics) which make the product possible.
The principles of IPD ;
1. UNDERSTAND
CUSTOMER NEEDS AND MANAGE REQUIREMENTS
2. PLAN AND MANAGE PRODUCT DEVELOPMENT

Very few products are developed by an individual working alone. It is unlikely that an individual will have all the necessary skills in marketing, industrial design, mechanical and electronic engineering, manufacturing processes and materials, tool-making, packaging design, graphic art, and project anagement, etc. Development is normally done by a design team as an integrated approach. The team leader draws on talent in a variety of disciplines, often from both outside and inside of the organization. As a general rule, the cost of a development effort is a factor of the number of people involved and the time required fostering the initial concept into a fully refined product.Integrated product development (IPD) practices are recognized as critical to the development of competitive products in today's fast-paced global economy. Product development teams, particularly when team members are collocated, are a critical element of IPD practices to facilitate early involvement and parallel design of products and their processes. As a company grows larger and products become more complex, hierarchical organizations are established to master the increasingly large organization size, the technical complexity, and the specialization that evolves to master this complexity. This company growth also results in the geographic dispersion of people and functional departments. These factors inhibit many of the informal relationships that previously provided effective communication and coordination between functions. Functional departments tend to focus inwardly on functional objectives. This is often described as the functional bin. A hierarchical organization structure with enterprise activities directed by functional managers becomes incapable of coordinating the many cross-functional activities required to support product development as the enterprise moves toward parallel design of product and process and a focus on time-to-market. Product development teams (PDTs) are a way to address this complexity by organizing the necessary skills and resources on a team basis to support product and process development in a highly interactive, parallel collaborative manner.

Manuel Data Input (MDI)
A CNC machine is not always operated by the means of
a program.During apart setup, the CNC operator has to do a number of operation
that require physical movements of ythe machine slides , rotation of spindle,
tool change , etc.There are no mechanical devices on a CNC machine.The handle (Manuel
pulse generator) is an electronic, not a
mechanical unit.In order to operate a
CNC machine without conventional mechanical devices the control system offers a feature
called Manual Data Input or MDI.
The
MDI enables the input of a program data
into the system one program instruction at a time.If too many instructions were
to be input repeatedly , such as a long
program , the procedure would be very inefficient .During a a setup and for similar purposes , one or a few
instructions at a time will benefit from MDI.

Intelligent Control (Better)
Intelligent control is the process that drives an Intelligent machine to
attain its goal automatically.In other
words, intelligent
control is a kind of automatic control that can drive autonomous intelligent machines to reach their goals
without any interection or with the
least human interaction.The control of an autonomous robot would be an example
of intelligent control.
Like many advanced scientific disciplines or or sciences such as artificail
intelligence, knowledge enginnering, and robotics ,the discipline of intelligent
control has also not been defined with an unified view until now.Although a
suitable and general definition on intelligent
control is difficult to make, it is
necessary to give a definition for intelligent control , so that people could
define characteristics, develop technology, and compare research results of intelligent control in the
different countries.

and applications ,Zi-Xing Cai,

Intelligent Control (previous)
Industrial robots are becoming increasingly intelligent. In this context, an intelligent robot is one that exhibits behavior that makes it seem intelligent. Some of the characteristics that make a robot appear intelligent include the capacities to interact with its environment, make decisions when things go wrong during the work cycle, communicate with humans, make computations during the motion cycle, and respond to advanced sensor inputs such as machine vision.
In addition, robots with intelligent control possess playback capability for both PTP(point-to-point) or continuous path control. These features require (1) relatively high level of computer control and (2) an advanced programming language to input the decision-making logic and other “intelligence” into memory.

Scrap (new)
Scrap is left over from
every manner of product consumption.In any discussion concerning
the ferrous scrap industry ,a key principle to establish is that scrap is an
involuntary product.Scrap is either a
by- product of a manufacturing processes or a result of obsolescence.

Scrap(old)
The term ‘scrap’ is usually used for the leftover part of raw materials and it is limited to material that has some minor sales value. Metal shavings with a minor sales value would normally be classified as (Colin Drury, Management and cost accounting, p.210)
