1Nat�onal Occupat�onal Standards – CNC Operator

PROJECT BACKGROUND AND METHODOLOGY

PROJECT BACKGROUND

The Wood Manufacturing Council (WMC), Canada’s human resources sector council for the advanced wood products process�ng �ndustry, was formed �n 2001 to address the ser�ous sk�lls shortages in wood manufacturing facilities. An independent, non-profit corporation with a Board of Directors drawn from the industry, the WMC serves as a national forum bringing together employers, workers, educators, governments, and other �nterested part�es �n a strateg�c all�ance to analyze, identify and address the sector’s human resources challenges and to ensure workers have the right mix of skills to compete in the globalized markets that will dominate the 21st Century.

In 2008, the WMC undertook the creation of National Occupational Standards (NOS) for the occupation of Computer Numerical Control (CNC) Operators in the wood manufacturing sector. The goal of this project was to work with job incumbents and other stakeholders to develop and nationally validate the occupational profile for CNC Operators in the wood manufacturing sector, including a review of the scope of the occupation. Recent research by the WMC indicates that significant challenges face the advanced wood products processing industry. These challenges stem from the continuing decline in the availability of skilled human resources as well as the changing skills requirements of the occupation. Occupational standards can be used as the basis for program development, such as the creation of training curriculum or competency-based assessment programs. Occupat�onal standards also help �nform �nd�v�duals seek�ng �nformat�on for career development or for other labour market information.

METHODOLOGY

Steering Committee

A Steering Committee comprised of six industry experts led by the WMC was assembled to provide vital input and feedback over the course of the project. These experts were tasked with identifying the occupations to be profiled over the course of the project and played a key role in validating information. Steering Committee members were selected based on the need to ensure representat�on of compan�es of var�ous types and s�zes, sector assoc�at�ons, and reg�onal representat�on.

Subject Matter Experts (SMEs)

WMC staff and stakeholders identified SMEs who were invited to participate in the development process of the NOS through interviews and online discussion forums. SMEs were selected based on the need to ensure representation of companies of various types and sizes, sector associations, and regional representation. Job incumbents and their managers were asked for the�r �nput �n the process.

2Nat�onal Occupat�onal Standards – CNC Operators

Situational Analysis

A s�tuat�onal analys�s of the CNC operator occupat�on �n the wood manufactur�ng sector was created based on telephone interviews conducted with SMEs to collect anecdotal information on the occupation. A standardized interview guide was used to collect information on the job environment, typical profile of the job incumbent, perceived anticipated future trends and attitudes of job incumbents towards professional development. This information provides important and relevant contextual information about the occupation.

National Occupational Standards (NOS)

NOSs describe the skills and knowledge needed to perform competently in the workplace. To create the NOS for CNC Operators �n the wood manufactur�ng sector, �nterv�ews were conducted on-s�te and over the phone w�th operators, superv�sors and managers to collect deta�led �nformat�on on the occupat�on. Authent�c workplace mater�als were also collected. The process used for the NOS development is based on a combination of methodologies derived from DACUM, Competency Analysis Profile System, Functional Job Analysis (FJA), job analysis and competency modeling best practices. These combined techniques resulted in an in-depth understanding of the job and detailed definition of skills required for the job. The steps to be taken in this project to define the standards were:

Preparation for Interviews (research of relevant documentation) – �n preparat�on for the on-s�te �nterv�ews w�th �ndustry representat�ves, the consultant rev�ewed all relevant documentation related to the occupation (e.g. Standards developed by other countries, international and territorial/provincial occupational guidelines). This �nformat�on was used to develop an �n-depth understand�ng of the dut�es, challenges and key sk�lls requ�red �n the occupat�on. The consultant used th�s �nformat�on to help gu�de the d�scuss�on dur�ng the �nterv�ews.

Interviews – a ser�es of on-s�te and telephone �nterv�ews were conducted w�th operators, superv�sors and managers/company owners to collect �nformat�on to complete a s�tuat�onal analys�s as well as to collect data towards the creat�on of the NOS.

Focus Groups – A focus group was conducted us�ng an onl�ne d�scuss�on tool to facilitate the review of the initial draft of the NOS. Comments and feedback were used to mod�fy the draft to create a vers�on then presented to the Steer�ng Comm�ttee.

Validation of Standards - The present document was rev�ewed over the course of a 2.5-day val�dat�on meet�ng. Dur�ng th�s meet�ng, the standards were rev�ewed and approved by the members of the Steering Committee and industry representatives. Following the meeting, the consultant updated the standards with agreed upon revisions and the document was submitted to the committee members for a final rev�ew.


STRUCTURE OF REPORT

The NOS for CNC Operators in the wood manufacturing sector consists of the following sections:

1. Occupational Background: Human Resources and Social Development Canada (HRSDC) has developed a national occupational classification (NOC) for the occupation of CNC Operators in the wood manufactur�ng sector. A NOC “�s a tool for help�ng Canad�ans to understand the world of work. It describes duties, skills, interests, aptitudes, education requirements and working settings for occupations in the Canadian labour market. Statisticians, labour market analysts, career counsellors and individual job seekers use this system to organize and interpret statistics and other labour market facts.” The information reproduced in this report gives a broad and general definition of the occupation, based on the information gathered from the NOC.

2. Situational Analysis: The purpose of this analysis is to establish the general occupational profile for the occupation and provide contextual information for the NOS. Anectodal demograph�c data and �nformat�on on educat�on, tra�n�ng, exper�ence and human resources challenges are also presented.

3. National Occupational Standards (NOS): NOS deta�ls the sk�lls, competenc�es and knowledge requ�red for a worker to perform competently �n an occupat�on; �t �s structured �n the following way:

4. DACUM chart: DACUM stands for Develop�ng A Curr�culum. It prov�des a graph�cal representat�on �n a chart format of the sk�lls and competenc�es requ�red to perform competently �n the occupat�on. It �s a v�sual summary of the �nformat�on conta�ned �n the NOS.

�National Occupational Standards – CNC Operators

SITUATIONAL ANALYSIS

BAckgrOUNd ANd MeThOdOLOgY

The following is a situational analysis of the occupation of Computer Numerical Control (CNC) operator in the wood manufacturing sector in Canada. The purpose of this analysis is to establish a general profile for the occupation and provide contextual information for the National Occupational Standard (NOS). Anecdotal information was gathered for the purpose of gaining an overall understanding of the profile of the typical job incumbent. For an in-depth analysis of the wood manufacturing sector as a whole, the reader is invited to consult the 2006 final report of the National Human Resource Sector Study for the Advanced Wood Processing Industry in Canada entitled “Attract the Best-Building Capacity for a Sustainable Future”, available from the Council.

Job incumbents, their supervisors and company owners were contacted to conduct telephone interviews. The individuals contacted work in organizations of various sizes and with various wood related products. The interviews were conducted from January to May 2008. Much of the information collected is anecdotal.

OverALL INdUSTrY

CNCs are becoming increasingly important in the industry. CNC machines increase precision and production speed while reducing production costs. Although the initial investment in acquiring such equipment remains high, more small and medium sized companies are moving towards this type of technology to remain competitive with larger organizations and international players. CNC Operators work in a variety of wood manufacturing organizations and perform CNC related tasks on a number of different machines of varying complexity. CNC machines encompass a broad range of machines such as milling machines, routers, moulders, lathes, drills, cutters, and grinders. In the context of this document, the focus is on CNC routers and work centers.

CNC operators not only possess knowledge of the techniques required to work on the specific type of machine they are assigned to but must also possess computer skills. The level of computer expertise will vary from one organization to the next; some organizations require that CNC Operators have programming skills, while other companies will have a separate programmer which will require fewer programming skills from the CNC Operator. The complexity of the CNC machine will depend on the type of work required and the level of sophistication of the organization. Newer CNCs are increasingly easier to use and program. This NOS does reflect some components of programming and organizations can adapt the NOS to their needs, removing the programming component if not applicable.

deMOgrAphIc OvervIew

Gender

CNC operators, like non-computerized machine operators, are mostly male. Women are becoming increasingly present in organizations where there is a separate programmer for CNCs.


Experience

The CNC operator will often be selected for mathematical abilities and/or programming skills. In cases where there �s l�ttle programm�ng �nvolved, regular woodwork�ng mach�ne operators w�th an average of 3 years of experience are typically recruited. These regular machine operators will be given CNC specific training by the machine manufacturer or through internal training programs.

Language

Typically, the working language will be either English or French. However, depending on geographical regions, other languages might be used in the workplace. In some cases, basic knowledge of foreign languages might be useful when working with equipment from other countr�es or when h�r�ng �mm�grants.

Education & Training

The CNC operator typically has a high school degree and has successfully completed Grade 12 math.

Mach�ne operat�ons vary from one manufacturer to the next and from one type of mach�ne to the next. Colleges and universities offer basic courses in CNC operation while equipment vendors offer more specific training for their machines.

Organizations offer Health and Safety training specifically related to safe machine and tooling use, personal safety and workplace cleanl�ness and ma�ntenance.

ATTRIBUTES, SKILLS & KNOWLEDGE

Personal Attributes

The CNC Operator, similarly to any machine operator, is expected to be punctual, professional, respectful and loyal to the organ�zat�on. He or she must also possess excellent commun�cat�on skills and good teamwork abilities. The CNC Operator must also be able to deal with heavy workloads under t�me-sens�t�ve schedules.

Skills Requirements

The CNC operator should be comfortable using computers, regardless of the level of programming required. He or she must also be familiar with the specific woodworking techniques applicable to the machine such as optimal machine operation speed, tooling type and wood properties. While new CNC machines can be quickly learned by someone with little wood mach�n�ng exper�ence, an exper�enced wood mach�ne operator can eas�ly learn the add�t�onal skills required to operate a CNC and will be able to best assess quality and resolve woodworking �ssues.

Knowledge Requirements

The CNC operator should have grade 12 mathematical courses and basic knowledge of parametr�c programm�ng language. In add�t�on, the CNC Operator should have excellent mechan�cal apt�tudes and knowledge of woodwork�ng techn�ques.


OCCUPATIONAL ENVIRONMENT

Working Environment

CNC operators work �n a plant env�ronment. The no�se level var�es from one organ�zat�on to the next depend�ng on plant set-up. The spaces are generally well l�t. Organ�zat�ons are �ncreas�ngly using principles of Lean Manufacturing or similarly-minded philosophies to maximize workflow and efficient product mobility.

Physical Requirements

Wh�le there �s some strength requ�red to man�pulate raw mater�al, organ�zat�ons are �ncreas�ngly us�ng equ�pment such as suct�on cups, doll�es and l�fts to handle the mater�al. However, the CNC operator �s st�ll requ�red to move the mater�al and parts to and from the mach�ne manually. The CNC operator must also man�pulate tool�ng, and move mach�ne parts for ma�ntenance or troubleshooting issues and therefore may use more or less physical strength depending on the type of mach�ne and operat�on requ�red.

Technology and Equipment

The CNC operator w�ll use manual tools such as hammers, screwdr�vers, j�gs, measur�ng tapes, and cal�pers �n h�s/her da�ly operat�ons.

Human Interactions

The CNC operator w�ll �nteract w�th the programmer and h�s or her superv�sor. He or she w�ll also interact with the machine’s manufacturer to receive training, to resolve maintenance issues and/or for troubleshooting. The CNC Operator will also interact with other plant departments throughout the course of the day, such as assemblers, inventory, material handling, quality assurance, and other wood mach�ne operators.

OCCUPATIONAL CHALLENGES

The ent�re �ndustry �s currently exper�enc�ng several challenges �nclud�ng the shortage of qualified labour, the high Canadian dollar and the negative effects from the timber industry which are impacting the supply of raw materials. These challenges lead to instability in smaller organ�zat�ons wh�ch further lead to employee turnover.

While recruiting employees is difficult for the industry overall, CNC machines are very appealing to younger workers who enjoy working with computerized equipment. It is therefore less difficult to entice younger workers to work on CNC machines than it would be for regular woodworking mach�nes.

Globalization has resulted in the emergence of new competitive markets such as China and India. CNC machines are an integral part of Canadian wood manufacturing companies’ strategies to remain competitive with these global competitors. CNC machines ensure that the work �s done w�th cons�stent qual�ty, qu�ckly and w�th reduced waste at lower costs.
