Automated Approach to Cutting Fluid Maintenance - Castrol SmartControl.
22 March 2021.
Given their additional axes and greater complexity, five-axis machining centers and multitasking lathes require a higher level of care from the maintenance department. The SmartControl has been out for “about a year now,” Two versions exist. Both continuously monitor cutting fluids, checking values such as concentration, pH, conductivity, temperature, and flow rate, and notifying the user if one of these needs attention. The more advanced version can adjust some of these values automatically—if it reads low on concentration, the SmartControl will add concentrate, just as it will adjust the pH on its own by adding buffer as needed.

Vibration-Dampening Devices for Milling
Vibration risk is high in milling operations requiring long tool assemblies. The Silent Tools™ series includes CoroMill® 390 cutters and arbor milling adaptors designed for long reach face milling, deep shoulder and side milling, cavity milling, and slot milling.
Vibration-dampening control yields productivity gains of at least 50% for the shortest adapter lengths, and up to 300% for longer adapters in milling operations.
Vibration-Dampening Devices for Boring
Vibration is a frequent problem in boring operations, especially when machining with long overhangs. Sandvik Coromant’s vibration-dampening adaptors include a dedicated bridge-adaptor interface and internal coolant through the assembly. Devices are available for both rough boring and fine boring.
Greater vibration dampening control can boost productivity in boring operations by 50-200%.

Productivity Improvement of CNC Machines with Robots
- Robots also help speed up the production process of CNC machines.
- Robots and automation help reduce production losses by 25%; Automation saves the shop owner from procuring new machines every year and therefore saves expenses.
- In situations where 3 to 4 people were required to monitor the CNC machines, only a single person can easily monitor them after automation with robot.
- Therefore there is increase in machine productivity and operator productivity.
CNC gantry milling machining productivity is much higher than that of ordinary milling machines
CNC gantry milling machine can effectively reduce the time required for machining parts with high production efficiency, including motor time and auxiliary time, so the machining productivity is much higher than that of ordinary milling machines. It can realize the precision movement of the machine and reduces the labor intensity of the operator. The CNC gantry milling machine automatically completes the processing of the parts according to the pre-programmed program

CAD/CAM Options for Increased Shop Productivity
January 27, 2021
CAD/CAM is always rapidly developing. Manufacturing technology continues to evolve to increase productivity.
Mastercam’s Dynamic Motion toolpath engine has been expanded to include more machining situations, including 2D milling, 3D milling, and turning. We’ve also upgraded both the “basic” and “advanced” ends of the CAM spectrum with smarter drilling and more automatic multiaxis cutting. Mastercam’s Accelerated Finishing toolpath strategy is also closely tied to next-generation tool forms being released.
With regard to tool forms, our relationships with tooling manufacturers yield direct benefits to Mastercam users. The ability to import tool libraries and use strategies for an expanding range of tool shapes saves programming time in addition to time on the machine.

Reviewing the Possibilities with Live Tooling
JAN 13, 2021
Live tooling, as a component on a lathe, is specifically manipulated by the CNC to perform various milling, drilling and other operations while the workpiece is being held in position by the main or sub spindle. These components, whether BMT or VDI, are also called driven tools (as opposed to static tools) that are used during turning operations.

Important Points
At increased values of waterjet pressure, there is a clear increase of the MRR at higher numbers of passes, meaning that the material removal process becomes more efficient when multiple passes at higher traverse speed are preferred than single machining passes at lower traverse speeds.
For calculation of the cutting efficiency, in the literature, the concept is defined as the amount of material removed per unit mass of abrasive consumed.
For different abrasive mass flow rate values, the increase of machining passes leads usually to higher cutting efficiency in comparison to the efficiency of the single pass machining case, and the same is observed for increasing jet pressure, especially for the highest value of jet pressure where the efficiency for the case with eight passes is almost 1.5 times higher than that of the single pass case.
The authors conclusion: "it can be deduced that a correct combination of process parameters and number of passes can lead to an increase of cutting efficiency, and it was shown that the use of multiple passes is more effective at higher abrasive mass flow rate and jet pressure values."
So there is scope for productivity engineering to determine the right combination of process parameters for a job, machine and tool combinations.

Lower feeding amount, lower grinding depth and appropriately higher spindle speed should be chosen to obtain better surface quality. Lower feeding amount, higher grinding depth and spindle speed should be chosen to balance grind efficiently and surface quality.
