Exploring the Turning Machining Method

Turning machining method is one of the most prevalent methods in the field of mechanical engineering today. However, not everyone comprehends the definition, advantages, disadvantages, and various turning machining techniques. If you’re interested in turning machining, read the following article by Towavina for more detailed information.

1. What is Turning Machining?

Turning machining is a material cutting method by turning the workpiece and the linear movement of the cutting tool (which moves longitudinally or laterally) based on the turning process. CNC turning machining is the process of performing turning machining on CNC lathes. Machining on CNC lathes has several advantages over conventional lathes. Specifically, it offers faster machining times, higher precision in machining, and the ability to meet complex machining requirements.

2. Characteristics of the Turning Machining Method

If milling machining involves cutting through the rotational movement of the tool (while the workpiece remains stationary), turning machining operates based on the rotational movement of the workpiece and the linear movement of the cutting tool.

The cutting speed V primarily depends on the durability and resistance to wear and heat of the cutting edge.

Feed rate F is the distance the tool travels in one revolution of the workpiece. The depth of the cut is determined through the tool’s movement.

The turning machining method is commonly used to manufacture parts with circular shapes such as smooth shafts, cones, holes, eccentric parts, etc.

3. Some Turning Machining

3.1. Methods Outer Diameter Turning

Method Outer diameter turning is the most common method used to machine cylindrical surfaces. This method is employed to create various cylindrical shapes such as long, horizontal, and wide cylinders. Depending on the shape of the part being machined, suitable methods can be chosen such as automatic sizing or trial-cutting methods.

3.2. Turning Hole Method

Turning holes are a preferred method when users aim to create holes on the surface of a workpiece.

3.3. Thread Turning Method

Thread turning is a simple machining method that can be achieved using basic turning tools. The purpose of thread turning is to create spiral structures on cylindrical surfaces, such as threaded holes or shafts.

3.4. Cut-off Turning Method

Turning machining is a method used to cut off a part or a portion of the workpiece from the stock material.

3.5. Facing Method

Facing is used when users want to eliminate excess material from the end to create a more precise and smoother surface. Various types of tools suit this method, including straight tools, curved tools, dedicated facing tools, etc.

3.6. Grooving Method

Grooving is a method used to create a narrow and defined depth groove. The groove or part of it will have a shape similar to a cutting tool.

4. Advantages and Disadvantages of Turning Machining Method

4.1. Advantages

Precision in machining is high with lathes, minimizing significant concentricity deviations. This is the most suitable method for machining parts with circular or cylindrical shapes. Additionally, the lathe’s rotating axis can be utilized for finishing steps like grinding and polishing.

4.2. Disadvantages

The downside of turning machining lies in its difficulty in machining highly complex parts. Milling methods prove more effective when dealing with intricate components.
