Leather Nesting Problem Analysis
mainly consists on finding best layouts for a set of irregular shapes within large leather hides with irregular contours, which may consists of holes and quality zones. In this article the main aim is to contribute to the efficient resolution of the problem by exploring many different constructive procedures.
This Leather Nesting Problem consists of is a 2-dimensional cutting stock problem which is finding the best layouts in a set of irregular shapes in the boundaries of natural leather hides, whose contour is irregular. The natural leather hide may have holes and also zones with different quality levels. The surfaces of the leather hides can be very heterogeneous. There could be a many number of different quality zones sand holes of different …show more content…
The First laser was developed in the 1970's. A laser beam is generated in a glass tube with one side having perfect mirror and and the other having semi reflecting mirror. One of the mirrors is full reflective, and the other reflective 70% . The laser gas can be a mixture of He, CO2 and N2. This mixture of laser gas is commonly known as a CO2 laser. There are several lasing gas mixtures available and in use but, for high powered industrial lasers, the CO2 mixture is used. An external power source such as electrical power excites the atoms in the laser gas mixture. When the atoms becomes excited, it goes to the meta stablestate and it gives off a photon of light. This photon excites other atoms of the laser gas giving off more …show more content…
High fuel efficiency of the Prime Mover. ii. High depth penetration upto 6 inches. iii. Good quality Soil pulverisation , excellent tillage preparation and suitable for all types soil. iv. Tentative diesel saving upto 15% per hour due to better tractor performance.
v. Higher tillage acerage per hour (1.33 Acers/hr).
2. Low load on tractor
i. Very low load on tractor. ii. Observed 37 hp tractor for 5 feet Jadhao Falc. iii. Observed 42 hp tractor for 6 feet Jadhao Falc. iv. Low maintainance of tractor.
3. Low cost of ownership and maintenance
i. Simple design hence very low maintenance and ownership cost an Rotavator and tractor.
4. Tentative Machine Life
i. High quality build supported by heavy duty tiller board and a rugged strong gear box coating with a 2 stage superior anti corrosive paint technology ensures longer life.
5. Tentative savings per working season
i. Fuel cost -500 acres /500 working hours /year makes saving of Rs.32500 per annum. ii. Maintenance cost comparative savings Rs.7000 per annum. iii. Net saving of Rs.39500 per annum.
5. Value Additions
i. Safety ii. Easy maintenance. iii. Stable Machine. iv. Long Skid.
v. Exports to developed countries.
