¸ßÅâÂÊÁùºÏ²Ê

While many shops invest heavily in CNC machine tools and related equipment, the implementation of new metrology strategies tends to happen more slowly. As a result, part inspection can remain a throughput bottleneck.

Tell me if this sounds familiar. After completing a workpiece, an operator ventures away from his/her machine to the quality lab so that a ¸ßÅâÂÊÁùºÏ²Ê inspector can perform first-article or other measurement routines beyond what the operator’s conventional hand gages can support. In some instances, the operator has to wait for the lab’s ¸ßÅâÂÊÁùºÏ²Ê to become available, too. Finally, if inspection shows that the part is out of specification, the operator has to return to the machine, make necessary adjustments, create a new part and jump back into the ¸ßÅâÂÊÁùºÏ²Ê queue to await another inspection routine. During all this time, of course, the machine isn’t making parts.

If this currently happens under your roof, perhaps it’s time to switch things up by bringing ¸ßÅâÂÊÁùºÏ²Ê measurement capability to your machine operators.

Proactive shops that did this in the past often enclosed their ¸ßÅâÂÊÁùºÏ²Ê in an air conditioned room. This put ¸ßÅâÂÊÁùºÏ²Ê inspection near machines, but not necessarily right next to them. However, shopfloor ¸ßÅâÂÊÁùºÏ²Ê technology has advanced a great deal over the years such that highly accurate measurements can be attained without an enclosure. That’s largely because today’s devices combine hardware and software elements to cancel out the influence of a facility’s fluctuating ambient temperature.

Shopfloor ¸ßÅâÂÊÁùºÏ²Ês have also become easier to operate and are available in a variety of styles, including the traditional bed-type version as well as articulating measurement arms. In addition, they are compact enough to be easily installed next to a machine. Some even offer the mobility to be moved to other machines.

Of course hurdles related to comfortable practices and conventional thinking often must be overcome. Machine operators, who feel secure using hand gages, need to become just as comfortable operating a more advanced measurement device. Plus, management might have to be convinced that the benefit of a more efficient operator is worth the cost of advanced shopfloor inspection devices.
