What are the factors affecting the tool life?

7 Factors Influencing Tool Life | Metals | Industries |…Factor # 1. Cutting Speed:Factor # 2. Physical Properties of Work Piece:Factor # 3. Area of Cut:Factor # 4. Ratio of Feed to Depth of Cut (f/d):Factor # 5. Shape and Angles of Tools:Factor # 6. Effect of Lubricant:Factor # 7. Nature of Cutting:

What is the hardest cutting tool material?

cubic boron nitride. It is nearly as hard as diamond. diamond. The hardest known material, but can only be used up to 600 °C and can’t be used to machine steel.

How do you calculate tool life in minutes?

Find the tool life equation if a tool life of 80 min is obtained at a cutting speed of 30 m/min and 8 min at 60 m/min. ADVERTISEMENTS: Tool life T2 = 8 min, cutting speed V2 = 60 m/min. Hence, Tool life equation becomes VT0.3 = C.

What is Tool and Tool life?

The life of a cutting tool can be terminated by a number of means, although they fall broadly into two main categories: Gradual wearing of certain regions of the face and flank of the cutting tool, and abrupt tool failure.

What is tool life?

Tool life definition: Tool life is the duration of actual cutting time after which the tool is no longer usable. There are many ways of defining the tool life, and the common way of quantifying the end of a tool life is by a limit on the maximum acceptable flank wear.

How do you stop wearing tool?

If the wear land becomes excessive or causes premature tool failure, reducing the cutting speed and optimizing coolant usage can help. High Efficiency Milling (HEM) toolpaths can help reduce wear by spreading the work done by the tool over its entire length of cut.

How can I improve my tool life?

How to improve tool life in turningReduce cutting speed, vc (to reduce heat)Optimize feed, fn (for shortest cutting time)Optimize depth of cut, ap (to reduce the number of cuts)

Which is main criteria to increase the tool life?

As identified in the text, tool life criteria used in production include (1) complete failure of the tool, (2) visual observation of flank or crater wear, (3) fingernail test to feel flank wear, (4) sound of the tool, (5) chip disposal problems, (6) degradation of finish, (7) power increase, (8) workpiece count, and (9 …

What do you understand by tool wear?

Tool wear is the gradual failure of cutting tools due to regular operation. Tools affected include tipped tools, tool bits, and drill bits that are used with machine tools. Types of wear include: flank wear in which the portion of the tool in contact with the finished part erodes.

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 is tool life equation?

With the slope, n and intercept, c, Taylor derived the simple equation as VTn = C where, n is called, Taylor’s tool life exponent. The values of both ‘n’ and ‘c’ depend mainly upon the tool-work materials and the cutting environment (cutting fluid application).
