Drilling is cutting method where a drill bit is used to make a circular cross-section in any solid material. A drill bit is a multi-point rotary cutting tool. It is attached to the machine that makes it rotate at speeds ranging from hundreds to thousands of revolutions per minute. This, when pressed against the workpiece, creates the desired hole by cutting off chips from the workpiece.

The US and China are considered to be the major manufacturing hubs using computer-aided design (CAD) software. China and the US together contributed about 45% to the global R&D spending in 2015.In APAC, the governments of various countries have taken initiatives like cabinetlevel programs in China, and the Skill India and Make in India program in India. The Machine Tool Association in Japan and Korea Institute of Science and Technology in South Korea have invested in the growth of the R&D of machine tools. This, in turn, will impact the industrial machinery market in APAC.This report covers the present scenario and the growth prospects of the global CAD market in the industrial machinery industry for 2016-2020.

Friction stir welding is a technique to join two metals or metal alloys via a solid-state joining process. The process makes use of a third tool that joins the two surfaces. The process involves the generation of heat that softens the surface near the friction stir welding tool. The two pieces of metal are intermixed at the joint, and mechanical pressure is applied by the tool to join the softened metal. Typically, this type of welding technique is applied in the case of aluminum metal (extruded aluminum) and on structures that require superior weld strength. The process does not need any postweld heat treatment.

A compressor is an instrument that is designed to supply air or gas at a higher pressure through compression. There are mainly two types of compressors: positive displacement compressors, and continuous flow compressors.
