The first step in replacing dull tools is recognizing when a tool is dull. If you’re leaving this judgment solely to your operators, it’s likely that you are experiencing some inconsistencies in the replacement of dull tools.
The importance of improving the task of dull tool replacement is related to the frequency at which cutting tools become dull.
With most user-created canned cycle applications for custom macro, you must provide a starting position from which the custom macro will begin its operation. In many cases, this leads to some redundancy in programming because the cutting tool may already be in the starting position prior to the G65 command that calls the custom macro.
The primary reason companies perform preventive maintenance on their production equipment is to minimize, if not eliminate, unpredicted downtime. Potential problems should be corrected before they cause machine components to fail.
Every company I’ve visited has at least some unwritten rules. These rules are related to things that experienced CNC people sometimes take for granted. Certain company methods may be considered so basic and obvious that there is no need to document them—or even to talk about them.
How to determine program-zero assignment during touch-offs.
Custom macro B users tend to struggle with the concept that variables can be vacant. To fully master custom macro B, you must understand the concept of vacancy and its implications.
What is an acceptable percentage of spindle run time for metalcutting CNC machines such as mills and lathes?
Regardless of how tool changes are actually made, it is imperative that the cutting tool currently in the spindle matches the program segment that uses the tool.
Constant surface speed (specified by G96 on most machines) is a turning center feature that automatically determines the appropriate spindle speed in revolutions per minute (rpm). This article details the advantages and disadvantages of using this feature.
