A PRSalpha Project:

The job required cutting multiple sheets of several different complex lattice patterns for use in walls of the set of a Broadway play. Parts were cut from 1/2" MDO with 1/4" compression cutter. Cut speed @ 6"/sec. [Project will be featured in the upcoming Newsletter.]

The sheets were held-down with vacuum. Vacuum was sufficient to hold the larger cut-outs so they could be cut out with a single pass. The smaller cut-outs were pocketed, by cutting from the center out to prevent small pieces flying loose. The first two video clips show the tool cutting the larger areas, the last 3 clips illustrate pocketing out the smaller regions. These parts were designed in ArtCAM and the tool paths include a 3D ramp into the material at the beginning of each of the cut-outs. This move produces a smoother cut and less wear on the cutter in operations like this with repetitive plunging. [Each of the Clips is about 1M.]

PRSalpha Project Clip - a -- PRSalpha Cutting a complex lattice. This clip shows cutting parts that are large enough to cut in a single pass and be held by vacuum.
PRSalpha Project Clip - b -- PRSalpha Cutting a complex lattice. This clip shows more cutting and positioning for large parts.
PRSalpha Project Clip - c -- PRSalpha Cutting a complex lattice. In this video clip, smaller parts are being pocketed.
PRSalpha Project Clip - d -- PRSalpha Cutting a complex lattice. The dust skirt has been raised in this video clip so that the ramping and pocketing strategy can be seen more clearly.
PRSalpha Project Clip - e -- PRSalpha Cutting out the a lattice panel.
