Manifestations: turbidity, thickening, uneven surface, brittleness, nail delamination and discoloration;
Symptoms such as deck inclination, contraction and falling off.
It is not recommended to go to an ordinary pedicure shop to treat onychomycosis, because the hygiene there cannot be guaranteed and it is easy to cross infection.
It is also not recommended to use internal medicine, because the side effects are great and it hurts the liver and kidney. Surgery or external application of drugs can be used.
Improvement method:
First: you should always cut your nails to avoid hiding dirty things under them, which will lead to bacteria invading your nails.
Second: can I use lotion when I get onychomycosis? First, Shu and An improved it. Keep applying it every day, and onychomycosis will be cured in about one to two months.
Third: You can also rub it with iodine, 3 to 5 times a day. A month later, the nails with white skin turned red and became longer.
Fourth: Pay attention to personal hygiene, wash hands and feet frequently, and keep the main skin dry and ventilated.

NC programming refers to the whole working process from part drawing to obtaining NC machining program.
(1) Analyze the part drawing and make the process plan.
The contents of this work include: (1) analyzing the part drawings, and defining the processing contents and requirements; Determine the processing scheme; Select the appropriate CNC machine tool; Select or design tools and fixtures; Determine the reasonable tool path and select the reasonable cutting parameters. This work requires programmers to analyze the technical features, geometric shapes, dimensions and technological requirements of part drawings, and combine the basic knowledge of CNC machine tools, such as the specifications, performance and functions of CNC systems, to determine processing methods and processing routes.
② Mathematical treatment
After the process plan is determined, it is necessary to calculate the tool center motion trajectory according to the geometric size and machining route of the part and obtain the tool position data. Usually, CNC system has the functions of linear interpolation and circular interpolation. For the machining of simple plane parts composed of arcs and straight lines, it is only necessary to calculate the coordinate values of intersection points or tangents of adjacent geometric elements on the outline of the part, and get the coordinate values of the starting point, end point and arc center of each geometric element, which can meet the programming requirements. When the geometric shape of the parts is inconsistent with the interpolation function of the control system, more complex numerical calculation is needed, and computer-aided calculation is generally needed, otherwise it will be difficult to complete.
(3) write parts processing program.
After the above process treatment and numerical calculation are completed, the part processing program can be written. Programmers use the program instructions of numerical control system, and write processing programs paragraph by paragraph according to the prescribed program format.
By inputting the programmed machining program into the numerical control system, the machining work of the numerical control machine tool can be controlled. Usually, the program should be tested before formal processing. Usually, the machine tool can idle to check the correctness of the movement and trajectory of the machine tool, so as to test the program. On the CNC machine tool with graphic simulation display function, you can check the program by displaying the tool path or simulating the cutting process of the tool on the workpiece. For parts with complex shapes and high requirements, you can also use free-cutting materials such as aluminum, plastic or paraffin to test the program. By checking the specimen, we can not only confirm whether the program is correct, but also know whether the machining accuracy meets the requirements. If we can use the same material as the machined parts for trial cutting, it will better reflect the actual machining effect. When we find that the processed parts do not meet the processing technical requirements, we can modify the program or take measures such as size compensation.
