What are the variables affecting tool life?
Factors affecting tool life
Finish required on the product. Machining conditions like temperature, the cutting fluid used. Machining variables – Feed, cutting speed, and depth of cut . Types of machining operation- continuous and intermittent cutting.
What variable influences the most the rate of wear of the cutting tool?
It is suggested that the cutting speed has the most important effect on the cutting force, cutting temperature and tool life, while the feed rate has great influence on surface roughness. The major wear mechanisms of the coated tool include abrasion, adhesion, oxidation and diffusion.
Which machining parameter has the largest effect on the lifespan of a cutting tool?
Cutting speed, v c , has a large effect on tool life.
Which of the following parameter will increase the tool life?
The variation of tool life with different process parameters has been plotted. Feed rate has the most significant effect on tool life followed by spindle speed and depth of cut. published works on metal cutting has regarded these three parameters as having the greatest influence on tool wear and tool life.
What are the major factors which affect the tool wear significantly?
Proper clearance will yield longer tool life. Sharp corners will show wear much more quickly than straight or curved edges, particularly on punches. Narrow sections will wear faster than heavier sections.
How can I improve my tool life?
- Control the Heat. ...
- Prepare the Edge. ...
- Design Tools Properly. ...
- Coating the Inserts. ...

How do you estimate your tool life?
- =cutting speed.
- T=tool life.
- D=depth of cut.
- S=feed rate.
- x and y are determined experimentally.
- n and C are constants found by experimentation or published data; they are properties of tool material, workpiece and feed rate.
How according to you does the grain size of the tool affect the tool life?
With increase of WC grain size, the tool end teeth flank wear length increases and the total cutting edge length reduction of the mill obviously increases . Thus, the micro end mill with finer grain size presents better wear resistance.
How tool life is affected by the cutting speed?
Cutting speed effects tool life greatly. Increasing cutting speed increases cutting temperature and results in shortening tool life. Cutting speed varies depending on the type and hardness of the work material. ... Increasing cutting speed by 20% decreases tool life to 1/2.
How does feed rate affect tool life?
Effects of Feed
Decreasing feed rate results in flank wear and shortens tool life . 2. Increasing feed rate increases cutting temperature and flank wear. However, effects on the tool life is minimal compared to cutting speed.
What is depth of cut?
Depth of Cut (t):
It is the total amount of metal removed per pass of the cutting tool . ... It can vary and depending upon the type of tool and work material. Mathematically, it is half of difference of diameters.
How do you stop wearing tool?
Reduction in tool wear can be accomplished by using lubricants and coolants while machining . These reduce friction and temperature, thus reducing the tool wear. n and C are constants found by experimentation or published data; they are properties of tool material, workpiece and feed rate.
Which liquid increases life of cutting tool?
The application of water jet reduces the cutting tool surface temperature and as a result tool life increases due to cooling effect of water jet [15]. High Energy Fluid Jet Machining can be used for micro-machining by reducing the jet diameter which is less than 100 μm.
How do I increase my tool life in milling?
- Understand Your Tooling Requirements. ...
- Consider Variable Helix & Pitch Geometry. ...
- Ensure an Effective Tool Holding Strategy. ...
- Run at the Correct Speed. ...
- Push at the Best Feed Rate. ...
- Use Parameters from Your Tooling Manufacturer. ...
- Utilize High Efficiency Milling.
