Interpolation The method by which contouring machine tools move from one programmed point to the next is called interpolation. This ability to merge individual axis points into a predefined tool path is built into most of today’s MCUs. There are five methods of interpolation: linear circular helical parabolic cubic All Read more…
Two types of programming modes, the incremental system and the absolute system, are used for CNC. Both systems have applications in CNC programming, and no system is either right or wrong all the time. Most controls on machine tools today are capable of handling either incremental or absolute programming. Read more…
The term numerical control is a widely accepted and commonly used term in the machine tool industry. Numerical control (NC) enables an operator to communicate with machine tools through a series of numbers and symbols. NC which quickly became Computer Numerical Control (CNC) has brought tremendous changes to the metalworking Read more…
Super plastic forming process (SPF) is appreciated tool for the fabrication of complex parts used in the aircraft and automobile industries.
HEAT TREATMENT The strength toughness of the base material are determined by its chemical composition and the heat treatment it undergoes. Low carbon steel is easily available and cheap having all material properties that are acceptable for many applications. Low carbon steel contains carbon contain of 0.15% to 0.45%. Heat Read more…
Thermo plastics These kinds of plastics have long separate and large molecules arranged side by side. The various types of thermoplastics are discussed below. Cellulose derivatives Cellulose nitrate is generally obtained by treating the cellulose with a mixture of nitric acid and sulphuric acid. It has high toughness, good resistance Read more…
Thermosetting Plastics The plastic which are hardened by the heating is called as thermo setting plastic. this heating reaction is non-reversible. The molecules of this type of plastic have a very strong binding force. The raw material for these kinds of plastics is available in liquid or solid form. These Read more…
Aerogel is a very special type of foam which is 99.8% air. Aerogel is a low-density solid-state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties, most notably its effectiveness Read more…
Material & Description ABS Good general purpose material, very tough yet very hard and rigid, good impact and electrical. Available in gauges from .040 to .475 with several extruded textures. Comes opaque and can be matched in custom colors. ABS/PC A blend or alloy of ABS and polycarbonate that thermoforms Read more…
Plastics are excellent materials with unique and very useful properties. You can produce just about anything you can imagine using plastics. Characteristics of Plastics History Of Plastics: 1. Before Plastics—Age of the Natural Resins Rubber—Tough elastic substance (light cream or dark amber colored) from the milky juice (sap) of rubber Read more…
