Have you ever thought about how life would be if we used primitive means to complete modern-day mundane tasks! Ideate using stones to carve tools for basic requirements like join pieces of wood together or at a macro level, to build infrastructure, hard work, isn’t it?
The purpose of tools has always remained the same since the time of conception. The world filled with sharp minds has found era-appropriate tools to reduce manual labor and increase productivity. To realize the efficiency and efficacy increasing over a while.
A. Why are cutting tools made of metals?
- Cutting tools are made from extremely hard alloys
- Extreme hardness is necessary to be able to machine other metals.
- Imagine cutting a PVR pipe in half with a kitchen knife, hard ain’t it? The motion is too less to dissect the pipe in half, making the friction lesser and the temperature lower.
B. What is the difference between cutting tools and machine tools?
- Cutting tools are used to get out the extra bit from a metal workpiece. It is mounted on a machine tool and provides no range of motion as being simply a tool.
- Machine tools are used to facilitate the motions required to cut a metal workpiece
C. What are the different kinds of metal cutting materials?
There are many kinds of cutting materials in the market, but the most regularly used ones are:
- Carbon Steel (CS):
- They have been used since the 1800s
- They lose their hardness at 200°C
- They are widely used for wood-works and non-ferrous metals
- They can be used in a router to machine aluminum sheets up to about 3mm thick.
- High Strength Steel (HSS):
- They have been developed since the 1900s
- HSS tools are tough and suitable for interrupted cutting, with a cutting speed of 10-60m/min
- They lose their hardness at 600°C
With so much to decipher, one blog post cannot do justice to the when and why of cutting tools, stay tuned for next week’s post for more information on the intricate details of these simple yet complex items blended so well with technology.
