SPC Reporting in Manual Post-Process Gaging

In a turning center, a manual post-process gaging system can include statistical process control (SPC) reporting.

A Few Interesting CNC-Related Websites

Here is a list of websites I frequently use to solve CNC-related problems and learn more about the subject.

A Flexible Turret Index Position

The cutting tools in your turning centers change on a regular basis. To minimize tool change time during setups, many setup people will simply load the tools required for the new job and leave tools in the turret from the last job as long as they don't interfere with the new job.

Combining Absolute And Incremental Motions

While we agree that the absolute mode should be your positioning mode of choice for most applications, there are times when incremental mode can be quite helpful. Repeating motions within a subprogram, for example, is one excellent example.

A Realistic Definition Of Cycle Time

Many people determine cycle time by measuring cycle start to cycle start time. As the operator presses the cycle start button, he or she starts the stopwatch.

A Tool To Help With Jaw Boring

Machining soft jaws remains one of the most tedious and time-consuming tasks for turning centers, so anything you can do to organize and simplify this task will speed up your setups. In order to make the workholding setup when soft jaws must be machined, the setup person must remove the current top tooling from the chuck, find the set of jaws to be used for the new setup, mount the jaws to the chuck, clamp on some form of temporary plug or ring, and machine the jaws.

Eliminating Calculations For Offset Entries

Almost every offset entry requires some kind of calculation to be made before the offset value can be entered. Say, for example, the target diameter for a turning tool is 3.
