2CNC Machines
Computer Numerical control (CNC) is the Automation of Machine Tools that are operated by abstractly programmed commands encoded on a storage medium, as opposed to controlled manually via hand wheels or levers, or mechanically automated via cams alone.
Modern CNC systems, end-to-end component design is highly automated using Computer-aided Design (CAD) and Computer-aided Manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine via a postprocessor, and then loaded into the CNC machines for production.

Basic CNC Principle
All computer controlled machines are able to accurately and repeatedly control motion in various directions. Each of these directions of motion is called an axis. Depending on the machine type there are commonly TWO to FIVE axes.
X,Y,Z – Axis Cartesian Coordinate System
X,Y,Z,A,B – Axis CNC Coordinate System
A: Rotary axis along X - Axis B: Rotary axis along Y - Axis

Programmer’s View
First motive of the programmer is to get the machine ready for production by changing the current program and then analyse the problem in the machine due to which the breakdown occurs.

71 ATC NOT WORKING
STAGE – 1 : Check the Problem using CNC Ladder Logic
Input of “Tool arrived” is not coming.a)Check the tool positionb)Fix tool in pocketc)Check other conflictsd)Bypass the input X067e)Look over the process for one cyclef)Handover the machine to Operator.
Result : Machine is ready for production
STAGE – 2 :Find Actual Cause of Problem
STAGE -3 : STAGE – 4 :KAIZEN POKA YOKE
STAGE – 5 : STAGE - 6WHY – WHY ? FAULT TREE

72INITIAL: X067 is NOCause : Limit Switch input is missing
ACTION : Bypass X067 (say with M054 NC)Result : Tool Clamped

73STAGE – 2 : Actual Cause of Problem a) Limit Switch input missing
b) PDB Not Working c) Strobe Length Increased d) Nut Opened.
STAGE – 3 : KAI ZEN - Change For Better
Limit Switch Proximity SwitchREPLACED
a) Increased Performanceb) Reliabilityc) Life about 15yearsd) Delay Decreasede) Easy to replace

74STAGE – 4 : POKA-YOKE Mistake-Proofing
BEFORE AFTER
This mechanism in a manufacturing process is that which helps an equipment operator to avoid (YOKE) mistakes (POKA). The purpose is to eliminate product defects by preventing , correcting , or drawing attention to human errors as they occur.
Using one NUT make the length of strobe increased on prolong use. Bt using two NUTs, one after other make it fix for long use which reduces human as well as mechanical errors. This helps in reducing required maintenance.
