Metal Cutting Machine Operations
The metal cutting machine operation involves manipulating a cutting tool to create, shape and finish a metal workpiece. Metal cutting machines vary in complexity but all require the same care and attention for safe and effective use. As with any precision machinery, operating metal cutting machines requires a thorough understanding of each machine’s capabilities, controls, and safety features.
Before engaging in any metal cutting operation, the operator must be familiar with the particular machine, its capabilities and its components. To ensure a successful and safe operation, proper training must first be provided and regular inspections must be conducted to identify any potential problems. Additionally, specific safety procedures must also be followed, such as wearing protective eyewear and proper clothing, including steel-toe shoes and long sleeved shirts and pants.
The first step of metal cutting is selecting the proper cutting tool for the job. Hand-operated, manually-fed cutting tools are the most common, but robotic tools are quickly becoming more widely used. Once a cutting tool is chosen, the machine must be adjusted to the proper speed and pressure to avoid over-cutting or strain. Usual cutting parameters include feed, depth and cutting speed. Feed, or the tool’s advance or retreat along the workpiece, is often controlled by a lever or knob on the machine. Depth regulates how deep the cut will be and is often set with a dial on the tool. The most important cutting parameter is speed, regulates how quickly and smoothly the tool moves across the surface of the metal. Highly skilled operators can adjust cutting speed for any kind of cutting operation.
The next steps in metal cutting include setting the machine to the proper cutting fluid and gas levels, as well as the workpiece’s clamping force. Different cutting fluids are used depending on the workpiece and the cutting rate, while several gases are often employed to reduce risk of sparks and fire. Clamp forces help secure the workpiece on the machine bed and must be strong enough to safely hold the workpiece without causing any damage.
The next step involves setting the type of cut, including the diameter and type of machining. Different cutting techniques are most suitable for different jobs, such as rough cutting and finish cutting. Once these settings are completed, the metal cutting machine can be engaged.
Finally, the operator must monitor production progress, make adjustments and inspect the metal workpiece after cutting to ensure quality. If the metal part does not meet specification, corrective measures should be taken to prevent rejections.
In summary, metal cutting operations must be conducted carefully and methodically as any discrepancies could lead to costly mistakes. Operators should be thoroughly trained and must strictly adhere to safety procedures and machining parameters. Quality should also be monitored on a regular basis to ensure that a finished product meets all necessary specifications. The use of metal cutting machines can provide high-quality products in a timely, cost-effective manner.
