non-standard cutting machine
problems and respond
is the world machine tool production than any other country, but in
the international competition in the market is still at a low level;
Even if the domestic market is also facing a grim situation, on the
one hand the domestic market for all kinds of machine products,
particularly non-standard cutting tools have secondary processing
a lot of
demand, on the other hand there are a lot of poor sales backlog of
domestic machine tool, machine tool products flooding the market
abroad, secondary processing of non-standard cutting tools in
China's market share is only about 15%, while 95 had reached 77%.
Seriously affect the
secondary processing of non-standard cutting tools for
This phenomenon, in addition to operational, manufacturing and
marketing tool superior quality reasons, one main reason is that
China's production of non-standard varieties of secondary processing
cutting machine tools, performance and structure is not advanced,
new products (including
variant and special machine tools) the development cycle, and thus
can not be timely for the user's needs to provide satisfactory
this problem is reflected in the following five areas:
(1) China's machine tool plant based products currently in
development cycle of about 15 to 18 months, including the design
time is about 5 to 8 months, about 40% of the total cycle.
some foreign advanced machine tool plant similar base-type product
development cycle of 6 to 9 months, including the design of about
1.5 to 2 months, only 25 per cent.
So whether it
is the product development cycle or the total proportion of time are
designed with foreign advanced level there is a big gap.
(2) the design of the factory due to the lack of scientific analysis
tools (such as analysis and evaluation of the software, the whole
structure finite element analysis method and machine performance
testing devices, etc.), self-developed new products are mostly based
on experience and intuitive analog design, design time
of success is
reduced, often requires repeated trial to stereotypes, and thus may
have missed an opportunity to market new products.
(3) Depending on needs of users, often in order to make some special
requirements, even when the product is about to put some users
temporarily put forward some requirements, which require rapid
variant design and modify the drawings and technical documents.
In other countries, this modification work on the computer with the
aid of only a few days to a week generally, and in China's machine
tool plant with manual operation for at least 1 to 2 months, and
because these drawings and documents involving multiple departments,
often occur Drain and
mistakes change phenomenon, affecting product quality and delivery
Now our plant design and process the majority of young people, their
lack of professional knowledge and practical experience, but also
charged with the development of the task.
(5) As long-standing design, process and discrete manufacturing
sector, the lack of effective collaborative development model can
not develop programs from the outset into the various aspects of
correct views, likely to cause repeated changes of products,
extending the development cycle.
To solve these problems, we must develop the whole process of
product integrated application of computer technology, the
development of optimization and simulation techniques to improve the
performance of the product structure, and established based on
concurrent engineering (Concurrent Engineering) for the design,
engineering and manufacturing personnel work and knowledge
shared virtual product development environment, using the
corresponding virtual product development software, so as to
effectively address the backwardness of product development, to
enable enterprises to achieve good economic returns.
