Axial Depth of Cut (ADOC): The distance a tool engages a workpiece along its centerline. Also referred to as Stepdown, or Cut Depth.
What is cutting depth in axial direction?
For the first-cut cases, the radial depth of cut s is defined as the distance that the tool penetrates through the workpiece at the ball center level through C axis, and the axial depth of cut a is the distance between the tool’s lowest point and workpiece’s upper face in the surface normal direction N (Figure 6).
Which two terms is axial depth of cut and radial depth of cut?
Axial depth of cut, ap inch (mm), is what the tool removes in metal on the face of the workpiece. This is the distance the tool is set below the unmachined surface. Radial cutting width, ae inch (mm), is the width of the component engaged in cut by the diameter of the cutter.

What is radial depth?
Radial depth of cut The depth of the tool along its radius in the workpiece as it makes a cut.
How do you measure radial depth of cut?
Calculating Tool Engagement Angle, Radial Depth of Cut
- r: Radius of the cutter = Diamater /2.
- a: TEA – Enagagement angle we are trying to find here.

Depth of Cut (t): It is the total amount of metal removed per pass of the cutting tool. It is expressed in mm. It can vary and depending upon the type of tool and work material. Mathematically, it is half of difference of diameters.
What is the difference between feed and depth of cut?
Cutting speed represents how fast the metal is removed from the workpiece. Cutting feed focuses on how far the cutting spindle travels across the metal part during one full rotation of the tool. As the cutting tool moves into the metal part, the distance that it moves is the depth of cut.
What is turning and facing?
Turning is used to generate cylindrical surfaces: generation of surfaces oriented primarily perpendicular to the workpiece axis are called facing. … The term turning, in the general sense, refers to the generation of any cylindrical surface with a single point tool.
Does step over relate to axial DOC or radial Doc?
Depth of Cut is also referred to as Axial Depth of Cut. Cut Width, also called Stepover, is the total thickness of the cut when viewing the cutting tool from above. It can be no more than 100% of the cutter’s diameter. Stepover is also referred to as Radial Depth of Cut.
Which of the following represent the formula for the depth of cut?
Explanation: (D1-d2) – this is the formula for depth of cut. Here both d1 and d2 are diameters and expressed in mm. 8. Which of the following represents the formula for metal removal rate?
What is the cutting speed at the Centre of a drill?
Recommended Speeds for Standard Materials with H.S.S. Drills
| Material | Recommended Speed (SFM) |
|---|---|
| Brass and Bronze (Ordinary) | 150-300 |
| Bronze (High Tensile) | 70-150 |
| Die Casting (Zinc Base) | 300-400 |
| Iron-Cast (Soft) Cast (medium hard) Hard Chilled Malleable | 75-125 50-100 10-20 80-90 |
What is depth of cut in milling?
The depth of cut is set at values found by multiplying the diameter or ball nose radius by a fixed coefficient. The image to the right shows a depth of cut standard for 2-flute, square corner, coated carbide end mill. If the workpiece materials are harder, the depth of cut should be decreased.
What is depth of cut in machining?
The depth of cut is the distance that the tool bit moves into the work. usually measured in thousandths of an inch or millimeters. … It is the total amount of metal removed per pass of the cutting tool. It is expressed in mm. It can vary and depend upon the type of tool and work material.
What is the minimum depth of cut for finish cut in milling?
As a general rule of thumb, the depth of cut should be no less than 2/3 of the nose radius. Avoid depths of cut smaller than 1/3 of the nose radius when finishing at small depths of cut.
What is a radial cut?
A cut through the center so the rings are at right angles to the face of the board is termed a radial cut or radial section. … In quartersawn boards, the log is sawed into quarters and then the boards are cut from each quarter so that the rings are nearly at right angles to the face of the board (see next image).
What is radial width?
Radial thickness is half of the difference between the outer and inner diameter of the main body part. From: The Design and Manufacture of Medical Devices, 2012.
What is radial engagement?
When we talk about the engagement of a male and female threaded fastener, it is commonly in the context of the length of engagement, which is often specified in order to prevent damage to the female thread by stripping or fatigue.
How do you give the depth of a cut?
Explanation: In lathe cross slide is used to give depth of cut.
What is the recommended depth of cut of for a slotting operation?
Grooving using end-milling cutters Full slotting with an end mill is a demanding operation. The axial cutting depth should be generally reduced to around 70% of the edge length.
Which material is used for cutting tools?
Tungsten carbide tools are commonly used for machining steels, cast irons and abrasive non-ferrous materials. Titanium carbide has a higher wear resistance than tungsten but is not as tough. … Tool Life Curves.
| Tool Material | Typical ‘n’ value |
|---|---|
| Cast Alloys | 0.1 – 0.15 |
| Carbides | 0.2 – 0.5 |
| Ceramics | 0.5 – 0.7 |
What is feed rate and depth of cut?
Feed, Speed, and Depth of Cut Feed rate is defined as the distance the tool travels during one revolution of the part. Cutting speed and feed determines the surface finish, power requirements, and material removal rate. … For most Aluminum alloys, on a roughing cut (. 010 to . 020 inches depth of cut) run at 600 fpm.
What is depth of cut in turning operation?
3. Depth of Cut. The depth of cut (t) is the perpendicular distance measured from the machined surface to the uncut surface of the workpiece.
What are turned parts?
A component that is subject to turning operations can be termed as a “Turned Part” or “Machined Component”. Turning operations are carried out on a lathe machine which can be manually or CNC operated.
How the feed & depth of cut is given to the shaper?
Deepness of cut is distance during which the tool digs in metal through its working stroke. … Feed of tool is distance to a cutting tool move to one side in two repeated cuts.
What is difference between shaper and planer?
The shaper is a mobile cutter, the workpiece is moved to perform the cutting process, a shaper is a light-duty machine, the shaper just can use only one cutting tool at a time; however the planer is different, it is a fixed planer that moves the workpiece closer to the planer for cutting, a planer is a heavy-duty …
What is the difference between cutting speed and spindle speed?
This relative linear speed is the Cutting speed. It is measured in meters per minute, different from the spindle speed, which is the number of revolutions per minute. The cutting speed is proportional to the spindle speed AND the diameter at which cutting is being done.
Why is facing operation done?
The purpose of facing are: To provide a true, flat surface, square with the axis of the workpieces. To provide and accurate surface from which to take measurements. To cut the workpieces to the required length.
What is headstock and tailstock?
Tailstocknoun. The sliding block or support, in a lathe, which carries the dead spindle, or adjustable center. The headstock supports the live spindle. Headstocknoun. A part of a machine (such as a lathe or drill) that supports a rotating part.
How facing operation is done?
Face milling operation Facing on a milling machine is the process of cutting a flat surface perpendicular to the axes of the milling cutter. This process removes the material by rotating the facing tool in the counterclockwise direction as the table feeds the work piece across the cutter.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
