目前，对于形状复杂不锈钢件来说，手工抛光还是占据了主要地位。手工抛光质量不稳定、效率低，影响产品的生产周期，从而影响其市场的竞争力。目前，只有少数大公司用全自动研磨抛光机。原因主要为价格昂贵、且只适于均匀抛光，故投资回报率低.现有的小型抛光机，其缺点是不能很好地控制载荷方位。因此发展半自动的不锈钢抛光机成了一种切实可行研究方向。既可以降低成本，减轻抛光工人的劳动强度，又可以提高效率，同时又不受企业经营规模的限制，可进行均匀和非均匀抛光。 本文首先分析不锈钢锅的发展和所要达到的效果，得到适合的抛光方式，在此基础上，利用AutoCAD软件为平面设计平台，对抛光机构进行了设计、建模。最后，研究抛光工艺参数 (主轴转速、进给速度等)对不锈钢体表面粗糙度的影响，通过知识获取，利用正向推理机制，建立抛光机磨轮机的总体构图。

Answer 1

At present, the complex shape stainless steel parts, the hand-polishing, or to occupy a dominant position. Hand-polishing the quality of instability, low efficiency, the impact of the production cycle, thus affecting the competitiveness of their markets. At present, only a small number of large companies use automatic polishing machine grinding. The main reason for the high cost, and only suitable for uniform polishing, so the low rate of return on investment. Existing small polishing machine, the drawback is not a very good position to control the load. Therefore the development of semi-automatic polishing machine for stainless steel has become a viable research direction. Can reduce costs, reduce labor intensity polishing, but also improve efficiency, while at the same time not subject to restrictions on the scale of business operations can be carried out uniformly and non-uniform polishing. In this paper, the development of stainless steel pot and the effect to be achieved by suitable polishing means, and on this basis, the use of AutoCAD software platform for the graphic design of the polishing body design, modeling. Finally, the study of polishing process parameters (spindle speed, feed rate, etc.) on the stainless steel surface roughness effects of knowledge acquisition through the use of forward reasoning mechanism, the establishment of polishing machine wheel machine the overall composition.

The
purpose
of
this

is
mainly
for

Its

in
the

once
this
happened
is
not

ideal
result,
welding
is
easy
to
make

to
burn
the
dangers.
Therefore
a
control
device
of
the
phenomenon
is
quite
necessary.
This
is
mainly
due
to
the
relatively
high
temperature
flamer
caused
by
such
devices
a

Mainly
in
oxyacetylene
