A method of appending M code cases

Mitsubishi Heavy Industries machine tool uses FANUC 31i system, the decoding principle is as follows: FANUC system F7.0 signal is defined as "auxiliary function gating pulse signal", symbol is MF, when the M instruction is executed, F7.0 is turned on, SUB25 is the function instruction, abbreviated as DECB, the meaning is binary decoding, which can decode 1, 2, 4 bytes of binary code data. One of the specified eight-bit continuous data is the same as the code data, and the corresponding output data bits are 1. As shown in Figure 1, in the DECB decoding instruction A represents the data type: it can be set  to 1/2/4 corresponding to the 1-byte/2-byte/4-byte data types, respectively; B represents the data address to be decoded; C represents the starting digital address of 8 consecutive digits of decoding; D represents the output address of the decoding result

For example: when the program executes M50, F10=50 at this time, and the above decoding instruction, M48 corresponds to the decoding output R746.0; M49 corresponds to the decoding output R746.1; M50 corresponds to the decoding output R746.2, and so on 8 consecutive numbers; Because the current program executes M50, the R746.2 coil is outputSince a decoding function instruction can only decode 8 digits consecutively, it is necessary to write multiple decoding instructions for decoding moreHowever, the DECB decoding command has a simpler way to complete all the decoding outputs at onceWhen the data type of decoding is changed from the original 1/2/4 to XX1/XX2/XX4, the decoding instructions can be executed in batches, where the single digits still represent the byte length of the

FANUC drive 8,9,A alarm how to troubleshoot?

FANUC servo drives are 8, 9, A and 8 in addition to the fan alarms that are most likely to occur.  9. A. Alarm, how to troubleshoot such an alarm?

1 Check the motor power line and motor resistance to ground, which can be detected from the motor end

It can also be detected from the drive side

Servo motor power line:

A---U (drive side) B---V (drive side)

C---W (drive side) D---G (ground side)

The resistance between UVW is generally about a few ohms, and the resistance value between them is almost equal. UVW resistance to G (ground) should be more than 100M ohms, the greater the resistance, the better the insulation.

Motor coil diagnostics:

Measured with a megohmmeter 500V

Good: >100MΩ

Start aging: 10~100MΩ

Severe aging: 1~10MΩ

Faulty: less than 1MΩ

Measuring from the driver end can eliminate whether the cable and power cable plug are short circuited or broken. 2 Exchange servo drive, or without servo drive, you can exchange bed XY axis (Lijia), generally XY motor is the same. Exchange the power line and feedback line directly from the drive end. This allows complete detection of cable and motor problems. The power line plug has a foolproof function, and you need to use a needle ejector (refer to the article: What should I do if the FANUC power line cannot be exchanged?). ）

3 Look at the running load of the machine tool, if the load is too large, repair the machinery. (1) Set the display operation monitoring screen parameter OPM (N0.3111#5) to 1. (2) Press the f

886 stroke switch, how to make the machine tool turn on without returning to zero?

Early FANUC motors were incremental position encoders that had to be zeroed in every time they were turned on, wasting machining time. How to change to not zero? 4 steps:

Step 1: Upgrade incremental position encoders to absolute position encoders

Step 2: Add a 6V battery to the drive

You can also choose a self-recharging battery box and never need to change the battery, the method refers to the video article "Never change the battery". 

Step 3: Check the encoder feedback line, whether there is a soldered 6V cable, as shown below (7-4):

Step 4: Modify the parameter 1815, near the mechanical origin, set 1815.4 and 1815.5 to 1

 For the setting method, please refer to the previous video "FANUC System Origin Setting"

410 alarm case study
 
1. Principle of servo feed system of CNC machine tool
On CNC machine tools, servo feed system is the connection link between CNC device and machine host, which receives feed pulse instructions or feed displacement information generated from the interpolation device or interpolation software, after a certain signal conversion and voltage, power amplification, driven by the servo motor transmission mechanism, and finally converted into linear displacement or rotary displacement of the machine tool table relative to the tool. The block diagram is shown in the figure.

2.Requirements for servo systems in CNC machine tools
CNC machine tool servo feed system as a kind of cutting tool and workpiece movement feed drive and actuator, is an important part of CNC machine tool, it largely determines the performance of CNC machine tool, such as CNC machine tool maximum moving speed, tracking accuracy, positioning accuracy and a series of important indicators depend on the performance of the servo feed system, so the accuracy and stability of the servo system is closely related to the normal work of CNC machine tools, The main performance requirements for the servo drive system of CNC machine tools are as follows:

1. The feed speed range should be large. 

2. The displacement accuracy should be high. The displacement accuracy of the servo system refers to the degree of consistency between the displacement amount required by the command pulse to feed the machine tool table and the actual displacement amount of the command pulse converted into the table by the servo system. The smaller the error between the two, the higher the displacement accuracy of

It’s no secret that COVID had a significant impact in the aerospace and aviation industry. The industry itself has seen a lot of fluctuation keeping manufacturers on their toes trying to keep up and plan for demand changes. As these demands increase for the aerospace manufacturing industry, the need to scale is ever prevalent. That is where aerospace robots come in to help manufacturers keep up with the demand.

In 2022 the aerospace industry was seeing a significant boom in A&D (Aerospace & Defense) demand. According to an article by FitchRatings.com, large commercial aircraft deliveries will increase in 2023 by more than 20% versus 2022.  This same outlook report also sees suppliers to OEMs benefiting from these numbers as aftermarket sales and maintenance, repair and overhaul (MRO) servicing will also see an increase in demand.

Jump forward to 2023. The buzz within the industry is that Boeing plans to increase production of their 737 Max aircraft. A recap of a press release by Reuters.com states that Boeing has plans to increase their monthly MAX production to 50 planes per month by 2026 while also ramping up their 787 production to 10 planes per month. Stan Deal CEO of Boeing is stated as saying that supply chain issues are “getting better” but are still working through training of employees brought on to handle the influx of post-pandemic orders.

But what does this mean for aerospace & defense manufacturing companies?
With the product demand growing, airplane manufacturers are struggling to stay on top of supply chain issues. That means they need their parts in house and ready for assembly. That is where vendors of aerospace and defense companies will see an influx in ordering. Along with production increases, all planes must go through FAA certification.

Stan Deal is also quoted as saying:

“The company is also making progress with the new 737 MAX 7 model and is in the process of completing final submiss

It’s no secret, airplanes are no small assembly project. These massive modes of transportation have an important job and carry the world’s most precious cargo, us. Most would be shocked to learn how much modern day plane builders rely on robots to ensure the public’s safety when in the air. Aerospace manufacturing robots do a variety of tasks that not only cover the building of the plane but also include several other applications such as cleaning, sanding and yes, even inspecting the plane.

Here are some ways we at EASYCNC support the Aerospace Manufacturing Industry:
Welding Robots
Machine Tending
Robotic Drilling
Inspection Robots
Aircraft Washing Systems
Let’s break these down a little bit…

Robotic Welders or Welding Robots
With the sheer size of aircrafts being what they are, it makes sense why robotic welders are seen so much in the aerospace industry. In order to meet any kind of a production quota, airplane manufacturers need to be welding several different parts of the plane at one time. While this poses a serious safety risk with human welders, robotic welders can run next to each other simultaneously with no issues.

The other factor to this equation is the unique materials with which aerospace vehicles are made of. Being able to weld nickel-alloy and titanium material requires quite a bit of advanced skill that the average human welder does not possess. These robotic welders can not only perform these welds but can do so with near 100% precision making them the obvious choice.

Robotic Drilling or Drilling Robots
Did you know a Boeing 777 has over 60,000 rivets? To implement these rivets manufacturers depend on drilling robots to get the job done. Not only does the idea of riveting 60,000 holes sound utterly exhausting, it also takes a human four steps to complete each rivet. This includes drilling the initial hole, additional drilling to the exact specified diameter, reaming the hole, and finally the rivet

The pharmaceutical industry is extremely competitive. It can be hard at times to keep up with your competition. EASYCNC’s robotic solutions can help speed up your production processes, improve consistency, and scale your business toward record breaking numbers.

EASYCNC Delivers Machine Uptime For the Pharmaceutical Industry

How Industrial Robots Support the Pharmaceutical Industry
Increased productivity
Better consistency
Reduction in downtime
Increased flexibility
Pick and Place Robots
Pick and place robots are seen more and more frequently in pharmaceutical manufacturing. Within these factories you can find everything from a LR Mate 200iD Series Robot to a Fanuc Cobot CRX-10iA Series. These robots are often used for picking up an item from a conveyor belt and moving it to a work area this is where the pick-and-place robot gets it’s name. Another popular task for these pick-and-place robots and cobots is sorting. More specifically the sorting and arranging of syringes and medicine bottles.

Inspection Robots
Advancements in robotic vision have seen an increase in the use of inspection robots in manufacturing. BusinessWire has recently predicted that Global Inspection Robots Market Size will increase 29% by 2028 as a result of this growth. Pharmaceutical Manufacturers rely on the dependability of these inspection robots to detect defects. Being able to consistently spot defects is vital in the pharma industry as any slight mistake could prove to be fatal for the end user. Some primary tasks these inspection robots perform are:

Inspection of the primary packaging – detection of prefilled syringes, inspection of the cap or tip and seals, and inspection of the exterior packaging for quality.
Product Inspection – leak testing and fill level verification of the interior product to confirm quality and volume of the product meets standards.
Secondary Packaging – Inspection of the label, vial counting, and serialization for US re

What is a cobot?
Simply put, cobots or collaborative robots are robots that are designed to work with humans. Cobots are unique in that they are able to learn multiple tasks to assist their human counterparts where the traditional robot is built and programmed to be not only stationary but also autonomous. These lower power robots are able to learn the majority of their tasks through demonstration and reinforcement learning thanks to multiple advances in robotic automation. The benefit of these lower powered robots is the increase in safety features that comes with collaborative robots. Cobots are the ideal solution for most small to mid-sized businesses looking to automate some of their production as they take up considerably less space but can also work in a variety of different capacities, they also help decrease workplace accidents as the robots are designed to be safe to be in close proximity with humans. They are essentially an extension of the employee giving them an extra set of arms to be able to complete the task.

Upgraded for safety
Cobots are different than your traditional robot due to the core standard ISO/TS 15066. Cobots have a variety of features that contribute to them being safe to work in tandem with humans.

Some of these features include:

Power, force, and torque limits — Simply put, these cobots are limited by power. They are able to apply a certain amount of force but should it for any reason exceed the limit the cobot is built to immediately stop.
Speed limits — The speed limit is important as humans work side by side with these cobots. By limiting the speed, the cobot cannot move fast enough that an collision with a human going full speed can cause harm. This means even though they are capable of moving fast, most cobots are designed to move slowly.
Safety-rated stop modes — Cobots have several triggers that may induce a stop mode to be employed. An “emergency stop” will only happen during an emergency
