- anco quality production thoughts on cnc punching

CNC Turret Punching

The CNC Turret Punch successively punches basic shapes (circles, rectangles, etc.) into sheet metals using hydraulic, pneumatic, or electrical power.  The sheet metal is first moved into an xy position where a ram containing a punch tool strikes from above and a die catches from below.

The shapes are selected from a rotating turret, (normally a multi-turret system) under CNC control.  They can normally hold anywhere between 20-70 punch/dies and switch between them taking around 600 strokes/minute.  Most have either a C type frame or a portal/bridge type fames, and range in size from 1 meter square bed with 20 tons of press capacity, up to 1.5 x 1.8 meters with 50 tons of press capacity.

It is faster and cheaper than laser cutting for basic shapes especially for high volume, although a laser cutter may be a better option for a design with many curves.

CNC turret punching has good edge control and can primarily is used in 2d shapes (airplane control panels, custom washers, auto parts, metal brackets, etc).  Some machines do bend, extrude, etc, while punching.

nice overview:

turret punching the musical:

• Common Materials:

Aluminum

Stainless Steel

Brass

Steel

Red Metals

Plastic

• Design considerations:

No fragile shapes

Wrapping may occur

No super small holes

Bottom side tends to differ a few thousandths of an inch from top side

Burrs are inevitable/consider burr direction

Mythical symbolism

Greek mythology, Psyche was also the ancient Greek word for ‘butterfly.’ She was portrayed in ancient mosaics as a goddess with butterfly wings.

Why are there boobs?  That was a common question….

We like to give things a beginning and an end, when it’s just not that simple… “Nature” is our own construct, the air in the fume box doesn’t disappear, that point on the map isn’t self contained.

Here at ITP, we create the demand for 100 or so pressure sensors/year (minimum).   That’s 100 microscopic bits of benzene we are supplying.  On one hand, in terms of the larger issues. that’s absolutely nothing (besides benzene is in cigarettes and plastics).  It doesn’t matter.  But on the other hand, it just does.

So, how should the pressure sensors ideally be made? Is that possible? Is that important?

audio and program still need tweaking.. .
