EXAMPLE:
Assume that a drilling operation is to be programmed as:
1. The tool is positioned at (25.4,12.5,0) by a rapid movement.
2. The tool is then advanced -10 mm in the z direction at a feed rate of 500 mm/min., with the
flood coolant on.
3. The is then retracted back 10 mm at the rapid feed rate, and the coolant is turned off.

What does a cnc miller do?
A CNC miller operates a computer numerical control (CNC) milling machine to create precision parts and components by removing material from a workpiece. They interpret technical drawings and specifications, set up the machine, select appropriate tools, and program the CNC software to execute the desired cuts and shapes. CNC millers must ensure high accuracy and quality in their work while adhering to safety protocols. Additionally, they may perform routine maintenance on the equipment to keep it in optimal working condition.
What are cnc spindles?
CNC spindles are high-speed rotating devices used in CNC (Computer Numerical Control) machines to hold and drive cutting tools. They enable precise machining operations by providing the necessary rotational force and speed for various materials, including metal, wood, and plastic. CNC spindles can vary in design, including air-cooled or liquid-cooled options, and are essential for achieving high accuracy and efficiency in manufacturing processes. Their performance directly impacts the quality of the finished product and the overall productivity of the CNC machine.
What is CNC manufacturing?
CNC stands for Computer Numerical Control. It refers to a type of milling or manufacturing machine that is computer guided, with the ability to change tools, bits, blades, or tips.
