Question

Reason

Solutions

·Tools breakage

·feeding too fast
·chip removal is too much
·blade length is too long
·too much abrasion

·reduce feeding speed
·reduce feeding speed of each tooth
·fixed handle, use shorter milling cutter
·early sanding

 ·Abrasion

·too fast
·too hard workpiece
·Cutting stacking on blade
·too small of main clearance angle

·reduce speed
·use high level material or cladding material
·change feeding rate and speed
·increase feeding rate and speed
·use correct cutting angle
·use larger clearance angle

 ·Blade passivation

·friction is too high in cutting
·workpiece is with high tenacity
·incorrect corner cut

·early sanding
·use high grade tool steel
·use correct cutting angle and clearance angle

 ·Notched blade

·feeding too fast
·feeding too fast in initial cutting
·inefficient stiffness of machine, tools and fixing tools
·loose workpiece
·lack of stiffness
·blade is too sharp

·reduce feeding speed
·reduce speed in initial cutting
·use machine, tool or fixing machine with better stiffness
·use shortest milling cutter
·reduce cutting angle and clearance angle

 ·Cutting stacking

·too fast cutting removal
·inefficient chip removal space
·inefficient lubrication

·adjust feeding rate and speed
·use less blade
·use air compressor

 ·Rough selvedge

·over abrasion of main clearance angle
·incorrest cutting set
·incorrect corner cut

·early sanding
·correct setting
·use correst cutting angle

·No perpendicularity on edge

·feeding too fast

·over cutting

·blade length is too long

·blade number is not enough

·reduce speed

·reduce cutting depth and width

·use suitable tool

·use multi-blade milling cutter

·Inaccurate size

·over cutting

·lack of accuracy for machine and fixing tool

·lack of stiffness for for machine and fixing tool

·blade number is not enough

·reduce cutting depth and width

·machine maintenance

·change cutting setting of machine, fixing tools and cutting

·use multi-blade milling cutter

·Noise

·feeding speed is too fast

·stiffness is not enough for mahine and fixing tools

·clearance angle is too large

·bad workpiece fixing

·cutting is too depp

·blade length is too long

·change feeding speed and rate

·use better machine or fixing tools

·reduce clearance angle

·fix workpiece

·reduce depth of cutting

·use shorter milling cutter or change cutting method

·Rough surface fine milling

·feeding too fast

·too slow

over abrasion

·no chip removal hook face on end blade

·reduce feeding speed

·increase speed

·early sanding

·reduce chip removal
