The selection principle of cnc milling clamping - POFI

The selection principle of cnc milling clamping - POFI: When machining parts on CNC machine tools, the basic principles of positioning and installation are reasonable selection of positioning datum and clamping scheme.

The selection principle of cnc milling clamping
Basic principles of location and installation
When machining parts on CNC machine tools, the basic principles of positioning and installation are reasonable selection of positioning datum and clamping
scheme. The following points should be noted in the selection:
(1) strive to design, process and programming calculation of the benchmark unification.
(2) reduce the clamping times as far as possible, and try to process all the surface to be processed after positioning the clamping once.
(3) avoid using the manual adjustment processing scheme of the machine, in order to give full play to the efficiency of CNC machine tools.

Basic principles for selecting fixtures
The characteristics of CNC machining put forward two basic requirements for the fixture: one is to ensure that the fixture's coordinate direction and the 
machine tool's coordinate direction are relatively fixed; The second is to coordinate the size of the parts and machine tool coordinate system.

In addition, consider the following:
(1) when parts are processed in small batches, modular fixtures, adjustable fixtures and other general fixtures should be adopted as far as possible to 
shorten production preparation time and save production costs.
(2) in batch production only consider the use of special fixture, and strive for simple structure.
(3) the loading and unloading of parts should be fast, convenient and reliable, so as to shorten the stop time of the machine.
(4) the parts on the fixture should not hinder the machining of the parts on the surface of the machine, that is to say, the fixture should be open, and its 
positioning and clamping mechanism components should not affect the machining tool (such as collision).

what is a Simulation Dinosaur? - Custom outdoor christmas decorations manufacturers from china-Hoyichi what is a Simulation Dinosaur? The simulation dinosaur is to use the modern technology means, according to the dinosaur fossil computer restoration pictures to produce realistic dinosaurs. The recreated dinosaur looks, shapes and movements are very lifelike, with lifelike shapes and lifelike movements. Simulation of dinosaurs can be more intuitive, more image let people understand the dinosaurs restore ancient dinosaur era style. The imitation dinosaur can let the child understand the dinosaur directly. There are two main techniques for making dinosaur replicas: First is the dynamic mechanical dinosaur, USES the steel bracket, dinosaurs and machinery, transmission, with high density sponge stereo processed muscle part of dinosaurs, and then joined on muscle fiber, increase the intensity of the dinosaur skin, finally after diluted with silica gel evenly brush to the dinosaur is formed...
