CNC machine tool processing technology analysis (2)

3. Analyze the processability of the workpiece structure

1) The internal cavity and shape of the workpiece should be as uniform as possible.

For example, the width of the shoulder retracting groove with the same diameter on the same shaft should be as uniform as possible, which can reduce the specification of the tool and the number of tool changes, and facilitate programming and improve the machining efficiency of the CNC machine.

2) The radius of the transition between the groove and the edge of the workpiece should not be too small.

The transition fillet radius reflects the diameter of the tool. The ratio of the tool diameter to the depth of the workpiece is related to the stiffness of the tool, as shown in Figure 3a, when R < 0.2H (H is the depth of the contour of the workpiece being machined) ), it is determined that the machining process of the workpiece is poor; as shown in Fig. 3b, when R>0.2H, the equivalent rigidity of the tool is better, and the processing quality of the workpiece can be guaranteed.

3) The radius of the bottom of the workpiece groove should not be too large

As shown in Fig. 4, when milling the bottom plane of the workpiece, the larger the radius r of the groove bottom, the worse the milling cutter's edge milling ability is. The maximum diameter of the milling cutter in contact with the milling plane is d=D-2r (D For the diameter of the milling cutter), when D is constant, the larger the r, the smaller the area of ​​the milling end edge milling plane, and the ability to machine the surface is correspondingly reduced.

4) Analyze the reliability of the part positioning reference

CNC machining should try to adopt a uniform reference positioning, otherwise the position error and shape error of the workpiece processing will be caused by the installation positioning error of the workpiece. If it is necessary to turn the workpiece on the CNC machine, it is better to use the machined outer circle or the machined inner hole as the positioning reference. If not, an auxiliary reference should be set. If necessary, add a process boss or a process hole to the blank, and then process the auxiliary reference after processing.

Ground Screw For Solar Power System

Ground Screw for solar power system is applied in fixation of solar panel. Pole anchor and Earth Anchor are fit for outdoor as the spiral pile mounting system adopts special materials that can resist corrosion, like HDG (hot dip galvanizing) and anodized silver15μm, screw pole mount system is adaptable for different soils. Additionally, it is easy to install. After it is removed, the vegetation can soon recover to reduce harm to surroundings.
Advantages:
1. Simple installation
There is no need to do welding or surface treatment, which saves time and cost. You just need to drill. Generally speaking, it just takes one day to install one screw pole mount system with 100-200 ground screws.
2. Large-scale application scope The screw pole mount system is suitable for different soils, like soft soil, bed rock, swamp and slope with more than 30°..
3. Spiral pile mounting system can work together with different support structures. The ground screw can be made according to client`s requirements.
4. Adaptable for different environment and environmental-friendly
There is no need to do much preparation for installation and there is no harm to environment during installation. Besides, ground screw can protect PV equipment and can be recycled.
5. Convenient transformation
Screw pole mount system can be transformed easily without damage to vegetations. Additionally, it is simple to reinstall.
the advantages of ground-screws for mounting solar photovoltaic systems
-Usually less invasive and landscape-altering than traditional mounting systems such as the half A-frames that are typically installed on cement slabs
-Screws can be easily adjusted to less serious gradients so mounting-frames are installed level: less complicated earthwork and engineering involved as compared to cement slabs
-More aesthetically pleasing than a cement mounting platform: shade-tolerant grasses and plants can easily grown beneath them
