Quantification of major good gotten from optimizing machine

High-speed, high accuracy machining technologies combined with advanced servo and spindle technologies have given some advanced CNCs innovative capabilities in order to help to increase the productivity of just about any machine tool. So, it is important to choose your CNC wisely. Many optimization features lie dormant waiting to be unleashed with a little investment. All machine tools have a boundary as to where it’s optimal performance lies. The performance boundaries can be best represented using a triangle (Figure 1) that shows the three keys to optimal performance: speed, accuracy and finish. Each corner of the triangle represents your best possible outcome for each of the key performance features of which your machine is capable. The length of each side of this triangle represents the amount of trade off your machine needs to achieve these performance features. (In Figure 1 all sides are equidistant; this may not be the case in every application.)

For example, machine ‘A’ needs to produce parts with the best possible surface finish, the faster the program is run the more the surface finish is effected due to servo or mechanical inefficiencies, and as you climb the speed leg you also sacrifice accuracy due to accelerations, inertia and servo lag. Operating dead center of the triangle is not ideal either since operating in that region means you are sacrificing performance in all areas. Optimization strives to reduce the length of each side of the performance triangle. The shorter the sides of the triangle, the faster, smoother and more accurate your machine tool can perform.

The benefits of optimizing your machine can be quantified in the following areas:

Productivity: Reduced cycle time can be achieved through the effective use of efficient part program features, coupled with optimized servo and spindle performance. Optimizing surface finish and accuracy could significantly reduce the requirement for secondary operations such as deburring or grinding.

Accuracy: By optimizing servo performance and acceleration/deceleration profiles, position error is minimized allowing greater accuracy at higher speeds.

Prolonged Machine Life: By smoother application of servo power through advanced contour controls, machine shock can be significantly reduced without sacrificing speed or accuracy.

Prolonged Tool Life: Through spindle power and feedrate optimization, even chip load can be maintained prolonging tool life. Through the use of effective tool management techniques, less operator intervention is required resulting in fewer interruptions due to tooling issues.

Energy Efficiency: Energy usage is quickly becoming a significant portion of overall operating costs. Energy costs per part can be significantly reduced by optimizing machine performance. Better control of the spindle and servo systems coupled with more efficient part programming techniques and processing all contribute to reduce the machining time per part. Better accuracies and finish, which eliminate secondary operations, also contribute to the energy savings per part.
