prismatic machining/programming

[shape]

hello everyone,

I know what parametric means but prismatic machining/programming... not a clue..

can anyone explain to me what means prismatic programming?

thanks all

It's one of those terms that means whatever the person using it intends it to mean.

Here, we use it to mean we're machining a prisim - ie, a 3D shape- in one go. For example, putting a block on a 4th axis attachment and machining 5 sides out of 6 in one hit. It's jargon really.

[pit202]

Prismatic Geometry - When checked, Edgecam detects areas of prismatic
geometry in solids based parts, including cylinders, cones and planar faces. 
This geometry is then inserted into the toolpath directly as arc and line moves,
rather than as a series of straight line approximations (as it is for areas 
of more complex geometry).

Is it that you asked ?

pit 202's quote suggest it is the same as Tool Path Filtering:

Filtering Toolpaths

With the toolpath filter you can replace multiple linear tool moves with a single arc move of a specified minimum and maximum radius. You can choose to create arcs in the XY, XZ, and/or the YZ planes, but the tool motion must be parallel to a machine axis to get the arc output. Setting the arc filter parameters allows you to smooth the faceting that is typical of linearized surface toolpaths, and create a single arc move out of several linear moves to reduce the amount of G-code produced.


I took this quote from: http://www.haascnc.com/solutions_3D.asp#3D

This webpage is a really good explanation of CAM and how to optimize the code that is produced.

A part that has planer faces. Creating toolpath and finding features on those Planer faces. Finding machinable pockets and drilled holes on multiple planes like, Top, Front, back, Bottom, Left & Right planes. A prism has multiple flat plane faces.
