Topology Optimization And Simulation To Inject New Power For 3D Printing

On increasing material manufacturing and reduce material manufacturing to collocation, there are two kinds of solutions on the market: one is the traditional machine manufacturers like Mazak, DMG Mori Seiki, Mitsui Seiki these traditional machine manufacturers will increase the manufacturing of laser cladding head integrated in the machine tool, and with the completion of "additive manufacturing" with "subtraction manufacturing". One solution is through flexible manufacturing systems such as Fastems will be a workpiece first through the "additive manufacturing", and then by the manipulator to heat treatment, then the manipulator will be sent to the machine tool for finishing workpiece.

In the view of increasing material manufacturer RPM and traditional machine operators will Okuma, increasing material manufacturing and reduce material manufacturing together with automation can create complex components, process without the need for casting and forging. Machine parts can ensure strict dimensional tolerances and surface finish requirements.

About the increasing material manufacturing and reducing material manufacturing reasons separately, we have previously introduced, Okuma consider the maximization of additive manufacturing and reduce material manufacturing potential approach is not the two kinds of technology integrated into the same equipment, because the processing environment and the processing speed is not the same, for the integration of the same equipment. When a technology in the processing, another technique in the wait state, the capacity of equipment is wasted. The two kinds of technology independent, intermediate by automatic machine or multi hand pallet system to achieve coordinated operation, can maximise efficiency.

The other is increasing material manufacturing and reduce material manufacturing for machining environment requirements are not the same. The design of laser deposition RPM system is to maintain the oxygen content is less than 10 ppm (PPM) to prevent the oxidation of the metal powder, the work area below the dew point of 50 DEG C.

RPM Robert Mudge on the basis of a more in-depth analysis, he believes that the increase in material manufacturing and reduce material manufacturing separately have three reasons:

Humidity control: the use of cooling liquid in machining process hinders the laser processing control in argon environment.

Material efficiency: in a special additive manufacturing equipment, metal powder mostly unused by powder recovery device dedicated to be re used. But in the mixed additive manufacturing equipment, let the powder (resulting in increasing material manufacturing process) and chip breaking (machining process) mixed together, to recycle powder becomes difficult.

Two processing: most by increasing material manufacturing complete parts need to heat treatment process before machining. The two processes are separated by special equipment to complete the intermediate heat treatment process becomes easy to join.

At present, increasing material manufacturing from the speed is not high, want to get thinner wall, processing shape is more complex, it needs to be adjusted in the deposition rate of powder. Many industrial parts, accomplished by increasing material manufacturing speed and machining is not so efficient, increasing material manufacturing a workpiece less for dozens of hours, but many are hundreds of hours.

We can consider a time to 40 hours through the increase in material manufacturing process to complete the parts are machined through the machine if you only need 10 hours, there will be two kinds of technology are integrated into one machine, while increased when material manufacturing, machine configuration is in the idle state, and the increase in material manufacturing done by separate device, you can release the machine idle this 30 hour capacity.
