Tech Tuesday: Advanced Rotary

Posted August 10, 2021 1:16 am   Published by    BobCAD-CAM ">

Tech Tuesday is a weekly blog that addresses some of the most common questions and concerns that I hear throughout the previous week from users of BobCAD’s CNC software. Both customers and future customers are more than welcome to leave a comment on what they would like to see covered for the following Tech Tuesday.


Advanced Rotary operations are found in the rotary options in the available milling operations. These advanced rotary operations are unlocked with our Milling 4X Pro package of BobCAD-CAM. There is a 4 axis advanced rough and 4 axis advanced finish rotary operation. Advanced Rotary operations give you a more optimized toolpath for your 4 axis milling needs.

4 Axis Advanced Rough

The purpose of the 4 Axis Advanced Rough operation is to utilize the rotary axis when roughing a part. In Addition to the standard rotary operation, the advanced roughing operation offers different cut patterns. Instead of only spiraling around or along the cylindrical stock, the advanced roughing offers an offset and spiral cut pattern. The tool will spiral around the even cylindrical areas, and then will pocket into uneven areas of the stock. This provides a shorter cycle time and more material removal in the roughing routine.

4 Axis Advanced Finish

The purpose of the 4 Axis Advanced Finish operation is to utilize the rotary axis when finishing a part. This operation allows you to focus on the specific geometry of the part to achieve a clean surface finish.

The Advanced Rotary operations also offer adaptive depth step options. You can set a standard depth of cut amount for each pass, and then there is a minimum depth of cut. This allows extra passes in areas that have more material remaining than in others. There is also an option to force floor cuts. This provides an extra pass at the full depth of any floor of a part to finish those areas.

These milling operations allow you to set certain limits in where you want to start and end the toolpath at. You can focus on a specific area of the part, whether you want to contain the toolpath in an area length-wise, contain the path along a certain area around the part, or both.

These rotary operations also provide a trim to stock option. BobCAD will trim away any toolpath based on the model created for your initial stock. This eliminates any air cutting and helps cut down on cycle times. You now have better control of the toolpath for your 4 axis rotary operations.
