has been successfully done and tested using an upright drilling machine. For different sizes of holes less than 20mm the tool can be changed. Similar designs can be made for any size and any number of sides to avoid lot of setting time and pre-machining procedures involved in current methods and very useful in case of mass production. INTRODUCTION Coimbatore is a highly industrial city. This is mainly due to entrepreneurship of local peoples. As there is no public sector undertaking. The

EXPERIMENT NO. 2 (A) Types of cutting tools: Single-point cutting tools can be classified by their motion as linear or rotator‚ depending on whether they rotate while cutting. Linear cutting tools include tool bits (single-point cutting tools and broaches. Rotary cutting tools include drill bits‚ countersink and counter bores‚ taps and dies milling cutters and reamers. Other cutting tools‚ such as band saw blades and fly cutters‚ combine aspect of linear and rotary motion. Following are different

This article is published with open access at Springerlink.com Abstract In experiments of machining hardened tool steels (such as AISI H11‚ H13‚ and D2‚ up to 56 HRC) by commercial Ø 0.5 mm square endmills‚ it is observed that the tested micro endmills showed severe wear at an early stage of the process due to chipping off around cutting edge corners

performance of the lens‚ one needs to generate finely machined surface with minimum roughness Single Point Diamond Turning machining is a technique which removes materials from a few microns to sub-micron level to achieve ductile mode machining on hard-to-machine materials such as electro less nickel plating‚ silicon‚ quartz‚ glass and ceramics with no subsurface defects. Such a machining process is able to achieve mirror surface finish of less than 10 nm and form error of less than 1um easily. If properly

removal is generally slow‚ but steady and continuous. Figure 1.4 shows the five main categories of wear. Abrasive Wear: * Abrasive wear occurs when material is removed from one surface by another harder material‚ leaving hard particles of debris between the two surfaces. * It can also be called scratching‚ gouging or scoring depending on the severity of wear. * Abrasive wear occurs under two conditions: * Two body abrasion: In this condition‚ one surface is harder than the
