Large portal milling machine with CNC with their own hands

Hello dear reader, in this article I want to share my experience building a milling portal machine with numerical program control.
 
 
Large portal milling machine with CNC with their own hands  
 
There are a lot of similar stories in the network, and I probably will not surprise anyone, but maybe this article will be useful to someone. This story began at the end of 201? when I was accumulating a certain amount of money with my friend, a partner in the development and production of test equipment. In order not to just skip the money (it's something young), they decided to invest it, after which the idea of ​​manufacturing a CNC machine came to mind. I already ...

Modeling of vibrations and noise in the transmission of the car

Modeling of vibrations and noise in the transmission of the carAt the work the transmission used for transfer of energy from the engine to wheels, strongly enough rustles. The first reason for this undesirable effect is that the transverse and axial forces resulting from the transfer of energy from one shaft to the other by means of a pinion have an undesirable mechanical effect on the bearings and the housing. The second reason is the flexibility of the various components of the gearbox, including bearings and housing, which can also lead to vibration. The variable stiffness of the gear clutch in the gearbox causes a constant vibration transmitted to the ...

BricsCAD Shape - free 3D CAD from Bricsys

Recently, under Linux, a new CAD product from Bricsis came quietly and almost imperceptibly, so Linux was supplemented with yet another must-have tool for virtual prototyping . The company Bricsis positions its product as absolutely free, a quote from the official website "BricsCAD Shape is free for all users and does not have any restrictions for commercial use."

Macro for Autodesk Revit, which trims the walls

Auto-Deck made the walls different, but the designers came and drew the walls at an angle of ??? and ??? degrees. Therefore, do not put the dimensions between the walls. This went on for a long time, but now the Great Macro Equalizer has appeared, it will return the walls to ??? and ??? degrees.
 
The macro corrects the walls, which are drawn with an error of up to 1.2 degrees relative to the parallel or perpendicular to the chosen wall pattern.
 
The algorithm is as follows: the user starts a macro, selects uneven walls by one piece or frame, then selects the wall of the sample, relative to which ...

New features of LISP in nanoCAD 8.5

Support for LISP in nanoCAD appeared a long time ago and was associated first of all with a special LSP command that opens a LISP-console intended for input of expressions and analysis of variables:
