Joker for CNC (WHY SO SERIOS?)

The text appears to be a comprehensive article on numerical control (CNC) machines. Here's a breakdown of the content: **History**: The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with motors to follow points fed into the system on punched tape. **Description**: CNC machines are automated tools controlled by a computer, which follows a coded programmed instruction. They use direct-drive stepper motors or servo motors for accurate movements. Commercial metalworking machines typically use closed-loop controls for accuracy, speed, and repeatability. **Parts Description**: Modern CNC systems are 100% electronically controlled, with the entire mechanism enclosed in a large box for safety. The controller hardware has evolved to provide more precise control over the machine's movements. **Examples of CNC Machines**: Other CNC tools include laser cutting, welding, friction stir welding, ultrasonic welding, flame and plasma cutting, bending, spinning, hole-punching, pinning, gluing, fabric cutting, sewing, and 3D printing. **Tool/Machine Crashing**: This is a problem that occurs when the tool or machine crashes into the workpiece, causing damage to both. It can be prevented by implementing safety features such as collision detection and avoidance systems. **Numerical Precision and Equipment Backlash**: CNC machines require high numerical precision to ensure accurate movements. However, equipment backlash (the amount of movement between the tool and the workpiece) can affect the accuracy of the machine. **Positioning Control System**: This is a system that controls the position of the tool or machine in three-dimensional space. It uses feedback from sensors to maintain precise positioning. **M-Codes**: These are machine-specific codes used to control the behavior of the CNC machine. They are typically used for tasks such as setting spindle speed, feed rate, and coolant flow. **G-Codes**: These are general-purpose codes used in CNC programming. They include commands for movements, tool changes, and other operations. **Coding**: This refers to the process of writing programs for CNC machines using G-code or M-code. It requires knowledge of CNC programming languages and syntax. **References**: The article provides references to external sources for further reading on the topic of CNC machines. In summary, the text provides an in-depth overview of numerical control (CNC) machines, including their history, description, parts, examples, and safety considerations.
