USAGE AREAS OF CNC IN INDUSTRY:
Today, the usage areas of CNC in the industry, the part of the industry that we call machining is the area where CNC is most widely used. We explained in our other blog that the birth of today’s CNC was caused by the problems encountered in this field.
When a triaxial milling machine was first put into operation in 1952, it was so perfect that it provided the solution to some of the manufacturing problems of the day. These systems, which are applied to milling machines, are then used for turning, grinding, etc. also applied to machine tools. Today, CNC is used in almost every field of production.
The main areas where CNC is used are;
Fabrication and welding.
Press forward Inspection and control.
Transport of materials
A- CNC LATHE MACHINES:
Numerical controlled lathes generally have two basic axes, X and Z axis. Many profile turning operations should be possible on such machine tools. These are done with linear interpolation (Linear Interpolation) and curvilinear interpolation (Circular Interpolation) operation feature. In addition, the number of revolutions and cutter replacement, the determination of the feed rate, etc. they have functions.
In CNC lathes with larger processing capacities, the number of axes can be 3 or more. The third axis can be the axis movement of the machine turret. The usage areas of CNC in the industry are to increase the structural resistance of the machine and to perform more precise manufacturing, especially in industrial type CNC lathes. In order to remove the chips from the cutting area, some design changes have been applied in the structural details.
As a result, CNC milling machines are the machines that have the most processing capability after machining centers in terms of the diversity of their operation capabilities. This type of workbench has the ability to operate on at least 3, 4-5 or more axes.
All variants of these machines are equipped with continuous track control (Continuous Paht Control). In addition, automatic cutter changing (Automatic Tool Change) is another feature of it. In addition, the cutter compensation (Tool Compensation) provides great convenience especially in curve milling operations and mold making.
It successfully performs the processing of three-dimensional (3 Dimension) workpieces with ideal profile and optimum properties. The cutters used are hard metal and titanium coated inserts with radius ends and high cutting speed.
B- CNC MACHINING CENTERS:
Such CNC machines are equipped with Point to Point and continuous track control (CPC). The manufacture of workpieces with such complex and multiple operations is carried out in one clamping.
a- Horizontal machining center
b- Vertical machining center
