About the optimum method for drilling composite test specimens, we are frequently questioned. Since composite materials are typically not included in machining handbooks, it is impossible to search up the appropriate cutting equipment or feed rates. Due to a lack of knowledge, composites machining can be somewhat of a dark art.

1.INTRODUCTION
Properties
A composite material is one that is created by combining two or more different materials, each of which has unique physical and chemical properties. Due to its low weight and affordable price, natural fibre has been taken into consideration in this article. Composites' initial phase is referred to as a matrix with a continuous character. This type of matrix material binds well, and the fibres have the desired ability to position themselves by transmitting loads to reinforcement.

The parallelism and perpendicularity of test specimens must adhere to rigorous ASTM criteria. This necessitates extremely exact machining. Cutting the samples to almost net form and then using a surface grinder to create the final specimen geometry is the simplest technique to attain high precision
Some composites provide exceptional defence against the worst conditions, including heat, oxidation, composition changes, and wear resistance. With the use of these varied properties, an architect can create structures with prospective results that are not achievable with common metals and materials. For applications that work well with solid materials, composites innovation also leverages a variety of laminate orientations.

2. OBJECTIVES OF WORK
Improvements are made to manufacturing processes, composite materials, and material science. Composites are versatile materials with unexpected mechanical properties that can be changed to suit the requirements of a particular application. Some composites provide exceptional defence against the worst conditions, including heat, oxidation, composition changes, and wear resistance. With the use of these varied properties, an architect can create structures with prospective results that are not achievable with common metals and materials. For applications that work well with solid materials, composites innovation also leverages a variety of laminate orientations.
The main objective of work is to examine the machinability of the natural fiber, polymer fiber and hybrid that is mixture of natural and polymer fiber at 0 degee orientation and also to perform stability test for the same material. The natural fiber used here is jute and glass fiber.

Based on the applications of design and development on necessary mechanical property, jute woven mats are stacked on top of each other and joined with epoxy resin to create laminated composites for usage in household and automotive equipment. According to a literature review, several researchers created sandwiched hybrid composites using the
