Walking Through Programming:suits wll for robots used in welding,spray painting etc.Programme is not concerned at all about cycle time which is controlled independently.The hands and arms of robot are initially moved manually and these movements are stored in computer memory for being followed during further operations.(Manufacturing Processes Second Edition,J.P. Kaushish)
Lead Through Programming:requires the operator to move the robot arm through desired motion path during a teach procedure,thereby entering the program into the controller memory.There are two methods of performing the lead through teach procedure:Powered lead through and manual lead through.(Industrial Automation and Robotics,A.K.Gupta)
Patterned Features:Pattern features are value of patterns., there should be more than one pattern feature or pattern groups for one object,pattern features are associated with specific objects.A patterned feature is obtained using a procedure with some operations in a fixed area of an image.(Advances in intelligent computing,Bernadette Bouchon-meunier,Ronald R. Yager,Lotfi Asker Zadeh)
The Squaring Shears:It has some peculiar parts.The bed is rigid horizontal crossribbed channel section.The top of the bed has two transfer T slots for the front and bevel gauge.It also has graduations for setting the front gauge and a large depression in the center of the bed to give clearence for grasping the metal.The crosshead is the horizontal beam connecting the housing for supporting upper cutting blade and hold down clamp. The housing is made of two vertical standards supporting the crosshead and of truss constructions.THE foot treadle is used to force the cutting blade together when cutting metal.The hold down acts as a clamp for holding the metal in place and serves as a safety guard.The extens ion arms and front brackets are for supporting the front gauge.The two graduation scales for selecting gauges are located conveniently on the top of the bed.The front gauge can be fastened in the T slot on the bracket and for the purpose of making straight or angular cuts.The side gauge is located in each side of the bed and is used for squaring the corners of the sheet metal.The bevel gauge is attached to the bed of shears for making angular cuts.The bac gauge is mounted on the rear of shears and is used for cutting large pieces of metals.(Industrial Technology,J. Dagoon)
about the word squaring shears you should write the page too.
