11 LEARNING GUIDE Week No.: __2__ TOPIC/S Introduction to Bench work EXPECTED COMPETENCIES Upon completing this Learning Module, the student will be able to: 1. To explain and define BENCHWORK and identify its importance. 2. To identify the different HAND TOOLS and ELECTRIC HAND TOOLS. 3. To be able to know the different LINEAR MEASUREMENTS. CONTENT/TECHNICAL INFORMATION BENCHWORK is concerned with the ability to use all types of hand tools and operation of power driven machines like electric drills, electric grinders and etc. BENCHWORK is important in all fields of technology because basically, a technician must be able to use any type of hand tools as well as understand the theory and principles involved. Bench work is a term used to describe any type of labor or work that is managed using a workbench rather than with the use of heavy machinery in a plant setting or in a larger area. The term is also sometimes used to refer to the structures that support finished projects such as model train sets that are set up on a more or less permanent basis. With all applications, the idea is that the labor is completed at a stationary setting rather than relying on machinery to do the job. In terms of the creation of goods, there are several different examples of bench work. Carpentry bench work involves the crafting of different types of furniture or frames for upholstered furniture pieces. Here, the idea behind the bench work furniture creation is to carefully craft each component by hand, with some pieces built and assembled entirely on the workbench. At other times, the individual pieces are hand crafted as part of the bench work and assembled at another site. A. BENCH WORK HAND TOOLS AND ELECTRIC HAND TOOLS The following are the different types of hand tools and their respective operations.  HAND TOOLS 1.
