Continuous Improvement-Sustaining the Effort

This program explains the basics of Computer Numerical Control, or CNC, by featuring segments on: Computer Numerical Control Principles and Computer Numerical Control Programming. The CNC Principles segment highlights the rectangular coordinate system and its use in generating precision tool paths. Integral elements of the rectangular coordinate system are presented, including: program zero, coordinate points, coordinate polarity, the absolute mode, the incremental mode, quadrants, and the various axes of motion. The CNC Programming segment features the step-by-step examination of CNC part program commands and their various letter addresses and numeric values. Also presented are discussions of point-to-point positioning, contouring, interpolation, compensations, special programming features, manual programming, computer-aided part design, or CAD, and computer-aided manufacturing, or CAM.

Cutting tools have many shapes, each of which is described by its angles or geometry. This program, part of the Fundamentals of Tool Design Video Series, explores single-point and multi-point cutting tool geometries as well as the machining variables that affect the cutting tool design.

Deburring processes are used to finish sharp, undesirable part edges that are produced during cutting and stamping operations. This program includes information on an array of deburring processes including cutting processes, power brushing, bonded abrasive finishing, mass finishing, abrasive blasting, abrasive-flow deburring, thermal deburring, and electro-chemical deburring.

Design for Manufacture and Assembly (DFMA) is a proven design methodology used to optimize part costs and quality, while reducing time-to-market development. This program features an interview with Nicholas Dewhurst of Boothroyd Dewhurst. He explains the concepts and use of DFMA in product analysis to understand the drivers of cost, and the interaction of the individual pieces within the product to optimize design, manufacturability, and assembly.
