1, what is CNC machining?
Nc machine tool is to process data and parameters input, machine tool control system to operation and control of the input information, and constantly send movement pulse signal to the drive system, driving system will be treated as pulse signal conversion and amplification, and then machine driven by a drive mechanism movement, so as to complete parts processing.
2, CNC machining generally includes what content?
1) Analyze the drawings and determine the processing area;
2) the geometry of the structural processing part;
3) According to the processing conditions, select the processing parameters to generate the processing path;
4) Tool path analysis and simulation;
5) Start processing;
3. What are the control actions of CNC system?
1) Spindle start, stop, speed and steering control;
2) Coordinate, speed and feeding mode of feed coordinate axis (straight line, arc, etc.);
3) Tool compensation, tool change, auxiliary action (machine locking/loosening, cooling pump and other switches);
4. What are the common CNC systems?
Funuc, Siemens, Fidia, Heidenhain, Fagor, Num, Okuma, Deckel, Mitsubishi
5. What is the main difference between ordinary milling and CNC milling?
The feed movement of common milling is mainly single axis movement, while nc milling realizes multi-axis linkage.
6, CNC milling processing is commonly used tools?
Face milling cutter, end milling cutter, disc milling cutter, Angle milling cutter, keyway milling cutter, cut milling cutter, forming milling cutter.
7, CNC machining needs to consider the cutting elements include those?
The main factors to be considered are the maximum cutting efficiency and spindle speed. The maximum cutting efficiency is determined by feed speed, tool depth and lateral feed. Spindle speed affects cutting speed and feed per tooth per turn.
8. What are the comprehensive factors that affect cutting?
1) Machine tool, rigidity, power, speed range of machine tool, etc
2) Cutter, cutter length, blade length, diameter, material, number of teeth, Angle parameters, coating, etc.;
3) workpiece, material, heat treatment performance, thickness, etc.;
4) Clamping method (workpiece fastening degree), pressing plate, vise, etc.;
5) Cooling mode, oil cooling, air cooling, etc.;
9, how to classify CNC milling processing?
Generally according to the number of axis can be controlled at the same time and mutually independent classification, common have two axis processing, two axis and half processing, three axis processing, four axis processing, five axis processing.
10, what is the object of four axis processing?
Mainly used for processing single impeller blade, cylindrical CAM, etc.
