Problems with CNC Machining

CNC machinery can have problems arise, and some of these problems are more common than others. When these problems occur, FlexCare+ steps in to get them resolved for you and back on track for new or current customers. These problems can include: 

# 1 Fixturing

CNC machinery can have problems when the workpiece that is being operated on cannot be gripped correctly by the work holding on the machine. A complex fixture can sometimes be as difficult to manufacture as the part it was supposed to hold. Besides this, it can also lead to vibrations and chatter during the process, and on occasion, an accident can happen.

#2 - Wrong Tools or Settings

By not picking the right tools or selecting the proper settings, you can have problems with your machinery or the product you may be working with. When this happens, the feed rate can be critical because if it is too low, the product will remain in the path of the cutting tool for too long and leave burnt or unwanted marks on the product.

#3 - Errors in Programming

A computer system controls these machines through the program that is installed. This system can cause issues in the programming and lead to product errors and mishaps. It is valuable to understand the G and M codes used in the controller and identify where these errors occur at.

#4 - Inexperienced Workers and Training

A computer system controls these machines through the program that is installed. This system can cause issues in the programming and lead to product errors and mishaps. It is valuable to understand the G and M codes used in the controller and identify where these errors occur at.

#5 - Machine Vibration and Chatter

Machine vibration can wear and tear on these CNC machines and the workpiece at hand. Your tools can deteriorate a lot quicker with the vibrations and will also affect the machine’s durability in the long run. They can cause problems within the spindle housing and within the machine bed itself. These problems can sometimes happen because of the wrong tool choice or supply settings.

Auto Stand-Off – This is currently defined to be surface stand-off and not to be confused with vector stand-off in 5-axis mode. The current auto stand-off is based on a changing surface and will adjust vertically based on the angle of the “A” Axis, so there is five (5) axis taken into account during the calculations, but this is not the same as the tool vector stand-off. There is the ability to do the vector stand-off change while the machine is running manually with buttons on the screen.

Z-Reader Probe – The Z-Reader is a device for mapping the location of the surface. It can be controlled manually & programmatically. The option is NOT active while cutting & is retracted out of harm’s way. It can be triggered to verify the surface at every pierce before the cutting process starts, or it could be used to drive surface mapping of the whole part before cutting starts. It begins with initialization or zeroing of the device to the surface at the beginning of a program and then accumulates or tracks the difference from that zeroing effort.

Automatic Edge Finder – The edge finder is or can be utilized manually (Jogging Method & Screen Buttons), programmatically (M & G codes), or fully automatic routine (dedicated program). This option sets offsets & program rotation to match the orientation & location on the cutting table.

AC Unit Installed on Electrical Cabinet – The unit is mounted on the cabinet’s High Power (480v) side. It is close to the location where the drives are mounted. This option keeps the cabinet temperature stable and allows heat dissipation faster. The servo drives for all axes are the most significant contributors to heat inside the electrical cabinet.

5-Axis Renishaw CalibrationThe calibration unit is a Renishaw model APCA45 with a modified spherical stylus. The device has a retractable cover and air purge to clear debris & dust during the activation process. It mounts to a swing arm controlled by a pneumatic rotary, so it is out of the way during regular operation and swings into the calibration position for calibration only.
