CNC TECH TALK MMS MAY 2018 36 Processes and Programming DEBURR ANY CROSSHOLE produced. The custom macro will stop the cycle once the final part count has been achieved. Maybe your machine operators primarily work in the metric system but must sometimes work in the imperial system. Find ways to keep them from having to perform any conversions between measurement systems. For example, utilize electronic measuring tools that can be easily set and calibrated for either measurement system mode. Incorporate programs that fully utilize the measurement system mode being used. That is, do not run workpieces dimen- sioned in the metric system with a program that has been written using the imperial system with converted coordinates. That way, all offsets can be specified in the measurement system origi- nally used to dimension the part. If you expect your machine operators to occa- sionally perform trigonometry calculations, find ways to help. A custom program on a mobile device could enable operators to input known values and receive the needed answers without performing the calculations themselves. For example, the machine operator may be measur- ing workpieces on a surface plate using a sine bar. Develop the needed calculation in a tablet or computer program that enables the operators to easily enter their measured value/s and make the mobile device respond with the answers they were previously calculating. These are but a few suggestions. As you walk the shop f loor, look for operators using calcula- tors. Then, be aggressively aware. Is there any- thing you can do to help? Given the potential for improving productivity, do not be too quick to say no. Indeed, good operators may think that simpli- fying calculation-related tasks is "dumbing down" the work they do and resent it. To a point, they are correct. Simplified tasks can be performed by people of lower skill levels. Make it clear that your goal is to free up some of their time, possibly so they do not have to work so hard to get their work done, or possibly so they have time to complete other, more important tasks.
