Follow operating procedures: Every machine or equipment has its operating procedures, and workers must operate in accordance with the procedures to avoid arbitrarily changing the equipment or machine settings.
Use of personal protective equipment: Depending on the nature of the job, protective equipment such as helmets, safety glasses, protective clothing, protective gloves, safety shoes, etc., may be required. These devices protect workers from injuries caused by accidents.
Regular training: Conduct regular safety training to ensure that all employees are aware of the latest safety regulations and operating procedures.
Keep the work area tidy: Cleaning up the work area can eliminate many potential hazards, such as avoiding slip and trip accidents.
Regular Maintenance Inspections: Equipment and machines need to be maintained and inspected regularly to ensure that they are in good working order. Any damaged equipment should be reported and repaired immediately.
Avoid fatigue at work: Fatigue can lead to poor concentration and increase the risk of accidents. Therefore, it is important to ensure that employees have enough time off.
Use the right tools: Using the right tools can reduce the risk of injury.

1.Learn how to keep safety

CNC Lathe: This type of machine tool is mainly used to process parts with various shafts, discs, sleeves, and various curved surfaces. They can perform a variety of operations such as cutting, boring, tapping, chamfering, etc.
CNC Milling Machine: CNC milling machine is mainly used to process various plates, sheets, shells, molds and other complex parts, such as some complex curves and surfaces.
CNC Grinding Machine: CNC grinding machine is mainly used for high-precision and high-finish processing, such as mold manufacturing.
CNC EDM Machine: This machine tool uses electrical spark for machining, mainly for mold making and cemented carbide machining.
CNC Cutting Machine: This machine tool is mainly used for cutting sheet metal, such as steel, aluminum, copper, etc.
Each CNC machine tool has its own characteristics and application fields, to choose the right machine tool, first of all, to clarify the type, material and accuracy requirements of the processed parts.

2.Learn CNC in indusrty: machine type, application

3. Make sure the machine ,material

Each CNC machine tool has its own characteristics and application fields, to choose the right machine tool, first of all, to clarify the type, material and accuracy requirements of the processed parts.

Determine the machine:
You need to choose the right CNC machine according to your machining needs. For example, if you need to machine complex surfaces or curves, you may want to choose a CNC milling machine. If you need to do a lot of shaft parts machining, you may need to choose a CNC lathe. At the same time, you also need to consider the precision, speed and reliability of the machine.

Determine the material:
The choice of material depends mainly on your product needs. For example, if your product requires high strength and wear resistance, you may want to choose steel or cemented carbide. If your product needs to be lightweight and corrosion-resistant, you may want to opt for aluminum or plastic. You also need to consider the processability of the material, such as machinability, heat treatment properties, etc.

Depending on your needs and budget, you may need to consult with a professional or machine supplier to determine the best machine and materials for you.

Programming of the program: First of all, you need to determine the machining process and tool route according to the drawings or models. Then, you can use dedicated CAM (Computer-Aided Manufacturing) software to write CNC programs. This program usually includes information such as tool selection, cutting parameter setting, tool path planning, etc.

Check the program: After the program is written, you need to check the program to make sure that there are no errors or omissions. Some CAM software provides a program check that can automatically detect and prompt possible errors.

Simulation of the program: Before the program is uploaded to the machine, you can use the simulation function to preview the machining process. This will help you identify possible collisions or cutting problems that can cause damage or waste in the actual machining.

Upload of the program: After the program is written and checked, you need to upload the program to the CNC machine. This is usually done through a network connection or a USB device.

Execution of the program: On the machine, you need to follow the program instructions to assemble the tool and position the parts. You can then start the machine and start the automatic machining.

These are just some of the basic steps, and the actual program setup and simulation may vary depending on the machine and software. If you are a beginner, it is recommended that you learn and operate under the guidance of a professional.

Open the gcode file through Note Pad

Find Z and find all the content in the layer (Z0.3-Z0.4)

Open the NC finder and paste the copied content

Click PLOT to generate

5.Try to read gcode

G-code, also known as the G programming language, is a programming language widely used in CNC machine tools and 3D printers. It consists of a series of characters and numbers that are used to guide the movement and operation of the machine.

G00: Quick positioning, this command allows the machine to move to the specified position at the fastest speed.
G01: Linear interpolation, this command causes the machine to move along a straight path at a specified speed.
G02: Clockwise circular interpolation, this command causes the machine to move along a clockwise circular path at a specified speed.
G03: Counterclockwise circular interpolation, this command causes the machine to move along a counterclockwise circular path at a specified speed.
G90: Absolute coordinate system, this command makes all position commands relative to a fixed origin.
G91: Relative to the coordinate system, this command makes all position commands relative to the current position.

The program first sets the absolute coordinate system, then quickly moves to the position of X10 Y20, then moves to the Z direction at a speed of 100 to -5, and finally moves to the position of X20 Y30 in a clockwise arc at a speed of 200.
