Numerical control machining is the same as CNC machining.
The production process is derived from the conventional machining technology of
daily life. It is an organic combination of conventional machining technology,
computer numerical control technology, computer-aided design and auxiliary
information technology. Due to the continuous innovation and development of
electric tools, more and more parts need to be precisely processed in modern
manufacturing, and the requirements for machining accuracy and surface
complexity of the workpiece are also increasing. Therefore, CNC machining has
received widespread attention, but in terms of saving resources and costs, CNC
machining is still more expensive than traditional machining time. The
following is our specific situation to introduce the difference between CNC
machining and traditional machining technology.
1. Machining
technology
In
the ordinary CNC machining process, whether it is positioning datum, clamping
method, tool, cutting method analysis, etc., it can be simplified through a
process, but the data and machining production process are more complicated,
and we need to carry out these influencing factors. Fully considered, and even
for the same machining task, the CNC machining process can have multiple design
solutions, and multiple machining parts and machining tools can be used as the
main line of development for construction process arrangements. The process has
more diversified characteristics , This is the difference between CNC machining
process and traditional machining process.

Power tools and fixtures
In
the CNC machining process, not only the coordinate direction of the fixture and
the machine tool must be determined, but also the size relationship between the
part and the machine tool coordinate system must be coordinated. In addition,
the two steps of positioning and clamping need to be effectively controlled
during the clamping process. Under the traditional machining technology, due to
the limited machining capacity of the machine tool itself, it is necessary to
perform multiple clamping during the machining. As well as the need to use special
fixtures, the design and manufacturing costs of fixtures have risen, which
invisibly increases production costs. The positioning of the CNC machining
process can be used to debug the instrument. In most cases, no special fixture
design is required, so its cost is relatively low.
3.
Tool
In
the production process of CNC machining, the selection of tools needs to be
analyzed and determined according to the machining technology and machining
methods. Especially in CNC machining, the use of information for high-speed
cutting can not only help improve the efficiency of machining enterprises, but
also the quality of processed products can be socially guaranteed, effectively
reducing the probability of cutting deformation and shortening the machining
cycle, so the demand for cutting tools Further increase.
