As a pre-requisite to improve your understanding of the following content, we recommend that you review the Histogram module and its discussion of frequency distributions. After early successful adoption by Japanese firms, Statistical Process Control has now been incorporated by organizations around the world as a primary tool to improve product quality by reducing process variation. Shewhart identified two sources of process variation:
It is extremely difficult to purchase straight shank drills over 13mm. Also, since most drills are manufactured with 13mm chucks maximum such a size chuck would be cheaper to purchase for assembly.
For marketing purposes it is a good idea to offer both imperial and metric sizes to the end user. Also, publish all information on chuck size in metric and imperial. Would dual voltage be advantageous for foreign exports markets. Will push cost of drill up to have this as a transformer and voltage selector switch will be necessary.
There are also no power requirements for the motor. What power is required from the motor? A watt motor will provide the capability of drilling 35mm in wood, 13mm in steel and 20mm in concrete.
Customer Decision — No. Stick with volt supply. We will adapt design in the future for foreign sales. Motor is to have a watt rating using the material cutting dimensions offered by the designer.
Capable of two speed operation — What are the two speeds to be? A good range, going by industry norm, would be and rpm. This allows the end user to obtain higher torques with the lower speed range but also the ability to cut efficiently with smaller drills using the higher speed range. How will the speed be controlled?
One standard solution is via a variable trigger on the butt of the pistol grip. Customer Decision — Use the speeds provided by the designer as this will correlate with the figures given for the different materials to be cut. Control will be via a variable trigger as is standard on many drills already on the market.
Have a hammer action — No comment to be made.
|Examples of Functional Requirements||Compliance Blog Design Specification Design Specifications describe how a system performs the requirements outlined in the Functional Requirements. Depending on the system, this can include instructions on testing specific requirements, configuration settings, or review of functions or code.|
|Product Design Specification (PDS) Essay Example | Graduateway||The Functional Requirements Specification documents the operations and activities that a system must be able to perform. Functional Requirements should include:|
|Medical Device Validation ABSTRACT The valid rational in developing statistical sampling for design verification and validation of a medical device product performance is to demonstrate the probability of conformance to specification of the device performance.|
|Intended Audience The information contained in this document builds on the Business Requirements Specification document and is technical in nature.|
|The system will be designed and built using the Microsoft BI Technology stack. This includes the following:|
Must have a hammer action. Operate continuously for long periods of time — What is considered to be a long period of time? Customer Decision — No answer to that. Suitable for soft and hard drilling — What is soft and hard drilling? All drills are reliant upon the type of drill bit being suitable for the material being cut.
Remove from PDS Eccentricity of drilling action must be limited to 0. To achieve this sort of accuracy it will be necessary to use very high quality bearings and gearing systems. This will push the cost of the drill up and also any benefit would be lost due to the fact that this is a hand drill and an end user will not be able to drill a hole with such accuracy.
Customer Decision — Use of standard sealed bearings and gears is to be allowed, as no benefit would be gained by using higher quality equipment. Have a minimum cable reach of 5m — Is the cable length that critical? Extension leads can provide adequate reach from the source of power to the drill.
The recommended length should be just long enough to allow freedom of movement for drilling. Longer cables represent trip hazards, increased material costs and cable stowage problems. Suggest the length be reduced to 2m.Statistical Analysis Statistical Reporting.
