G12 CIRCULAR POCKET MILLING
CNC PROGRAMMING G12 Circular Pocket Milling CW / G13 Circular Pocket Milling CCW (Group 00) These G-codes mill circular shapes. They are different only in that G12 uses a clockwise direction and G13 uses a counterclockwise direction. Both G-codes use the default XY circular plane ( G17 ) and imply the use of G42 (cutter compensation) for G12 and G41 for G13 . G12 and G13 are non-modal. * D - Tool radius or diameter selection** F - Feedrate I - Radius of first circle (or finish if no K ). I value must be greater than Tool Radius, but less than K value. * K - Radius of finished circle (if specified) * L - Loop count for repeating deeper cuts * Q - Radius increment, or stepover (must be used with K) Z - Depth of cut or increment *indicates optional **To get the programmed c...
MATERIALS USED IN INJECTION MOLDING - THERMOPLASTIC
THERMOPLASTIC THE THERMOPLASTIC ARE HEATED AND BROUGHT TO MOLTEN STATE IN AN INJECTION MOLDING MACHINE . THE MACHINE INJECT THE PLASTIC INTO THE METAL MOLD WHERE IT COOLED. AFTER SOLIDIFICATION OF THE PLASTIC THE MOLD IS OPEN AND THE THE COMPONENT IS EJECTED THIS PROCESS IS CALLED INJECTION MOLDING. THE OTHER PROCESS ALSO CAN TAKE PLACE IN THERMOPLASTIC MATERIAL I.E. BLOW MOLDING, ROTATIONAL MOLDING AND EXTRACTION MOLDING PROCESS(HOLLOW ARTICLES) Polystyrene (PS) Learn More About High-Quality Polystyrene Plastic Used in Injection Molding One of the most common plastics used in THERMOPLASTIC MATERIAL is polystyrene, a synthetic polymer often used when molding packaging and industrial components. Usually in the form of foam or plastic, polystyrene is a non-toxic and odorless material, and is one of the predominant plastics used in the food packaging industry as well as the automation industry. Its solidity and clarity make it useful for everything from automo...
