Modular Tower Workholding for CMMs
Phillips Precision offers a modular tower system as part of its Lean Inspection Arsenal workholding line for coordinate-measuring machine (CMM) inspection.
Phillips Precision offers a modular tower system as part of its Lean Inspection Arsenal workholding line for coordinate-measuring machine (CMM) inspection. First in the line of tower modules is a 2" interlocking system that can be built both vertically and horizontally. Cubes added horizontally can be turned to any angle and locked securely.
The modular system is intended to maximize the CMM work envelope without interfering with probe travel. A “building block” design enables users to determine the height of the setup. A staggered hole pattern adds flexibility for workholding. The modules enable building up the setup both vertically and horizontally. Horizontal cubes can be secured at any angle.
Preconfigured systems include several interchangeable components: an adjustable base, 2" × 2" cubes, a 4" blank spacer block, and 2" and 4" posts that connect the system and provide pivot points. Each cube has 10 (¼-20) holes per side for flexibility in holding positions and a 3/8-16 threaded center hole that allows cubes to be added horizontally. Highly accurate components are designed with male/female locating features and are made from black anodized aluminum.
Here are some of the tools and techniques for making sure machine tools stay at peak performance levels.
Measuring workpiece dimensions is relatively simple for machine operators but measuring workpiece geometry which involves more complex comparisons of part shape to an ideal shape--is now also practical on the shop floor. The gaging equipment for doing this is coming down in price while becoming easier to use.
Different instruments (and different operators) are prone to different errors.
