What is back boring cycle?
What is back boring cycle?
The boring bar must be set very carefully, it must be preset to match the diameter required for backboring, its cutting point must be set in the spindle oriented mode, facing the opposite direction than the shift direction. …
What is the need of back boring canned cycle?
In addition to boring the hole, this cycle shifts the X and Y Axis before and after the cut, to clear the tool while it enters and exits the workpiece (refer to G76 for an example of a shift move).
Why is it called a canned cycle?
Canned cycles automate certain machining functions such as drilling, boring, threading, pocketing, etc… Canned cycles are so called because they allow a concise way to program a machine to produce a feature of a part. A canned cycle is also known as a fixed cycle.
What is G76 code?
G-code G76 is a cnc cycle which is used for thread cutting on cnc machines. Threading cycle G76 is explained here G76 Thread Cycle.
What is the application of G87 code?
G87 Side drilling cycle is used to drill on the component diameter/side using driven tools. Fanuc G87 Side Drilling Canned Cycle works on FANUC Oi and compatible cnc controls.
What are the limitations of NC machine?
The disadvantages of NC Machine are as follows.
- A skilled person is required to punch the program on the tape and operate it.
- The equipment and tooling cost is higher than traditional machines.
- Maintenance and Investment cost will be more in NC machines.
What is P G76?
G76 – Two-line thread cycle 5; The ‘P’ word on the second line is the depth of thread in microns and the ‘Q’ defines the depth of the first cut. Finally, we tell the control the pitch of the thread using the ‘F’ value. With the G76 active the machine knows that we are using feed per revolution and not feed per minute.
What is G code used for?
Simply put, G-code is a software programming language used to control a CNC machine. And, even with complex CNC machining, G-code is written in a straightforward, logical way. A “G” is followed by a number, which is a command to change geometry. For instance, “G00” is a command for rapid movement.
