What Is in Feed in Woodworking
In woodworking, the term “feed” refers to the rate at which the cutting tool moves through the wood during the CNC machining process.
It plays a crucial role in determining the machining time, surface roughness, and accuracy of the finished area.
The feed rate can be adjusted to achieve desired outcomes, taking into account factors such as the material being cut, the cutting tool material, and the desired tool life.
The hardness of the material and the strength of the cutting tool also impact the feed rate used.
Additionally, the article emphasizes the importance of determining the optimal feed rate for achieving a well-machined part in CNC woodworking processes.
Did You Know?
1. Sawdust, a common byproduct in woodworking, is not only used as feed for various animals, but also as an ingredient in certain food products. It can be found in some brands of ice cream as a stabilizer due to its moisture-absorbing properties.
2. While it may seem unusual, certain wood fibers and shavings can be processed and used as feed for fish farming. The high cellulose content in these wood materials can make them a sustainable and cost-effective alternative to traditional fish feed.
3. Wood chips and shavings can also be utilized as bedding material for livestock, such as horses and poultry. The soft and absorbent nature of the wood can provide a comfortable and hygienic environment for the animals.
4. In some woodworking practices, the sawdust collected from specific types of wood, like cedar or pine, is used as a natural pest deterrent. By scattering sawdust from these woods around plants and gardens, insects and pests can be deterred due to the oils and compounds found in these specific wood varieties.
5. Certain woodworking shops and artisans collect sawdust to participate in a process called “biochar production.” This involves transforming the collected sawdust into charcoal-like material, which can then be used for soil enhancement and carbon sequestration in agricultural settings.

Understanding The “Sweet Spot” And Ideal Cutting Conditions
The “sweet spot” is a critical factor in achieving optimal cutting results, as it determines the relationship between speed (spindle rpm) and feedrate. Visualize a schematic that illustrates the ideal sweet spot matches for specific cutting conditions and materials. The green areas in this schematic indicate favorable conditions, while the red areas represent danger zones – running either too slowly or too quickly. Discovering the sweet spot is essential because tools can encounter issues like overheating or breakage when the flutes become excessively full.
Factors Affecting Tool Life And Performance In Woodworking
Two main enemies of tool life in woodworking are overheating and chip loading. These factors have a significant impact on the performance and longevity of tools. Unlike the hardness of metals, the characteristics that affect feeds and speeds for wood are related to the behavior of the sap in relation to the sawdust and how the chips are made.
Additionally, manufacturing processes can introduce abrasive grit embedded in materials like MDF and plywood, which further influence feeds and speeds. Therefore, it is crucial to understand the hardness and behavior of different wood types to ensure optimal tool life and performance.
Importance Of Feed Rate In Cnc Machining Processes
The feed rate plays a crucial role in determining the machining time and the surface roughness of the finished area in CNC machining. It can be adjusted depending on factors such as the material being cut, the cutting tool material, and the desired tool life. The hardness of the material and the strength of the cutting tool also influence the feed rate. Moreover, the cost of the tool and the quantity of parts being produced should be taken into consideration when determining the optimal feed rate. Achieving the right feed rate is essential for optimizing and ensuring the efficiency of CNC machining processes.
Determining The Optimal Feed Rate And Cutting Speed For Precision Machining
When it comes to precision machining, cutting speed and feed rate both play crucial roles in optimization and efficiency. While cutting speed does not affect scallop marks or surface finishes, the feed rate has a direct impact on them. The higher the feed rate, the higher the degree of scallop marks and surface roughness. Therefore, it is essential to differentiate between the feed rate and cutting speed, including their units of measurement and impact on cutting force and power consumption.
Determining the optimal feed rate and cutting speed involves considering various factors. The spindle speed serves as the foundation for determining both parameters and requires calculations to determine the feed per tooth and feed rate of the cutting tool. Achieving a well-machined part in CNC machining processes relies on determining the optimal feed rate and cutting speed. This determination should take into account factors such as material properties, tool strength, desired surface finishes, and tool life to ensure the precision and accuracy necessary for successful woodworking projects.

Frequently Asked Questions
What is feed in shaping?
Feed in shaping refers to the relative movement of the workpiece in a direction perpendicular to the reciprocating motion of the ram. In a shaper, the feed is provided to the workpiece as it undergoes machining. This movement is commonly measured and expressed as either mm/double stroke or mm/stroke since no cutting occurs during the return stroke. By controlling the feed, the shaper can shape the workpiece precisely and efficiently.
What is feed in cutting tool?
Feed in cutting tool refers to the rate at which the cutting tool is advanced along the workpiece relative to its cutting speed. It is essentially the velocity at which the cutter moves perpendicular to the cutting direction. The feed rate plays a crucial role in machining operations as it determines the amount of material that is removed with each pass and affects the quality of the cut. Controlling the feed rate is essential to achieve precise and efficient machining results.
What is the unit of feed?
The unit of feed in turning and boring processes is typically measured as distance per spindle revolution (inches per revolution [in/rev] or millimeters per revolution [mm/rev]). This is because the feed rate depends on the motion of both the tool and the workpiece. By aligning the measurement with the rotation of the workpiece, it allows for precise control and calculation of the feed rate in relation to the rotational motion.
What is feed in machine tools?
In machine tools, feed refers to the rate at which the cutting tool advances against the workpiece during one spindle revolution. Also known as feed rate, it determines the distance traveled by the cutter in a single revolution. This parameter is crucial in turning and boring processes, where it can be measured in either inch per revolution (ipr) or millimeters per revolution (mpr). The proper control of feed ensures optimal tool performance and efficient material removal, ultimately leading to precise and productive machining operations.
